First off, this did get me thinking more on Una's timeline. Not just this AU, but in general. It's not perfect since I'm not quite sure how time in DmD!Oz works, nor am I too far in the books yet (I'm still in the part where Amy acquires her Glamora styled room. I need to pick these books uo again 😅). But lemme go over that real quick.

Around the time the Witch of the West took over, Una's father, a winkie named Hubert (yes I'm making that canon XD) decided it was worth the risk and set off on his own, wanting to live freely from the Witch. The other winkies were too scared to follow him, and he was gravely injured by the time he made it outside the borders. But he was alive.

A bit before Dorothy came to Oz in the first place, Hubert met Twyla, an Ozian woman who would become his wife and mother to his child. She had possessed a tiny bit of magic, and was a great painter. Being a traveling merchant, she let Hubert tag along on her way to the Emerald City, and they shortly fell in love.

They decide to build a cottage in the woods together, choosing to live away from society to avoid any trouble with the Wicked Witches. Even after the news finally reached to them about how Dorothy slayed them (which again, they live away from people. It took a while 😅), they liked the life they built and chose to stay.

At some point during the war between King Scarecrow and Jinjur, which Twyla and Hubert were fortunately blissfully unaware of because they lived so deep in the woods, they have little Una. They fill the girls head with all the stories they have heard about the Witchslayer Dorothy and her companions, as well as The Good Witch Glinda. This, along with her mothers' limited magical skills, inspires Una to learn the ways of magic one day.

When Una was just 7 years old, however, Glinda had discovered the family's secret home purely by accident. For reasons unknown (did she see a threat in the family? Was it for control? Simple entertainment?), Glinda influenced Dorothy Gale to send the now corrupted Tin Woodman on a crusade to kill anyone he found in that forest. (Hubert had been the first to die, a blade through the chest. Then Twyla, after running as far as she could with Una in her arms and her own injuries, had her head ripped off right in front of young Una. Una just barely made it out alive, now covered in her mother's blood and the terrifying metal monsters eyes flashing in her mind).

Now, in this is when her timeline diverges in the AU. In the OG timeline, Una wandered the forest, tired and starving, for a week before she came across Mombi. As you know, Mombi took her in with The Order of the Wicked, and adopted her helped raise her to become the witch she is now. But in this AU, Glinda decided to follow Tin, to make sure the family was killed. When Una survived, she saw potential in the child, and 'saved' her, before taking the girl under her wing. By the time Una turns 20-24, in either timeline, I imagine that's when Amy arrives in Oz herself.

Now that I've gotten that out of the way, let's got onto the headcannons for this AU! I got a lot so hang tight 😅 and since I haven't read the books too far, I have no idea how accurate these are.

Una and Glinda

In the OG timeline, Una's mind does block out a little of what happened because the trauma was so severe. Enough where she doesn't realize that the Tin Woodman was the one behind her parents' deaths. But in this AU, Glinda encouraged her to forget. Distracting the girl, and maybe using magic to subtly erase Una's memory. Her subconscious fought it, but now Una can't recall what really happened that night now. She has nightmares of it, and knows that her blood parents were taken from her, but Glinda made her believe the 'great danger' they're fighting in Oz killed them.

In the OG timeline, Una is pretty strong, both physically and magically. She's had excellent training in the order. But here, Glinda keeps her as weak as possible while still training her. Una has very little physical strength, and although she has the potential to be very powerful. Glinda is careful with what she teaches her. But Una, with the help of Scarecrow, is starting to suspect her mother figure.

As you can see, Glinda has a lot of influence in Una's life. She controls what she sees and learns, and makes sure that she doesn't see what's really going on- not until she knows she has Una's undying loyalty. As such, Una is rather naive, and her spirit has been damaged with Glinda's manipulative ways; Glinda sweetly putting her down at the right moment, keeping her in the dark and making sure she believes she needs her. (But damaged does not mean destroyed). Yeah, as you can see, Una and Glinda are like Rapunzel and Gothel.

Of course, Glinda fills her head with lies about her aunt Glamora, Mombie, Granny Gurt, and all the other witches. Una had thought Glamora killed her parents, but of course, she's proven wrong.

Not important, but please imagine with me; Glinda singing the Mother Knows Best reprose to Una if/when she runs away (especially if she runs away with a possible crush I'm thinking up for her 👀). Also! In the Carrie Musical How Those Boys would Dance, but Glinda trying to place doubt in Una's mind about someone she loves. Also, this scene in Steven Universe when White Diamond and Steven finally meet. I'd have to dig into a lot of why Whites words are important, but imagine if Una was 'brought' back home from the order, or she runs away, and Glinda with her fake warmth treats this like it was all just a silly game played by a girl having a temper tantrum, "Did you get everything out of your system, dear?"

Una and Scarecrow

Scarecrow being a dad for Una- even if it's not the most genuine on his part- is getting to my heart so much 🥺🥺🥺 I can't possibly raise your headcannons, but here's what I have;

Una bonded with Scare, especially when he would treat her after Glinda punished her and he would complain to her about her during their late night 'dinners' (even if Una didn't want to talk that way about her, she did agree with some things he said. Especially as she grew older. It was what inspired her to be suspicious of her mother figure and teacher in the first place). As such, he's her first choice of person to go to when she's scared or hurt, especially if by Glinda, or if she just wants a hug (I mean, he is like a pillow XD).

Because of how close she and Scare have gotten, Glinda has pretty much appointed him as her Una Spy. He reports everything he can back to her (or at least he's supposed to)

Even though Glinda is her teacher, she has gone to Scare to help her with her homework or for extra lessons. After all, if there's anybody in Oz who can teach her anything, it has to be the smartest guy in the world, huh? If Scare isn't busy with his experiments, he'll happily take the opportunity to prove how smart he is- I mean, teach the silly little girl.

When Una joins the order (when she runs away, or Mombi kidnaps her for a plan, and Una proves her worth to join the order), she was in denial about Scare the most. That's her father! How could he be such a monster?? How could he... Know what Glinda had done to her parents and not do anything?? This can't be him, can it??

Also, Una would hug Scare a lot. Everytine she sees him. It's a comforting habit she gained when she was younger, and he took care of her. Even when he's a grum about it, Una will still give her straw dad a hug ^^ it does hurt a little if he pushes her away or act like this is such an inconvenience, but it's what she knows so she doesn't let it stop her all the time.

Now, if Una got to see Scarecrow after his brain is removed and the sweet, affectionate straw man is back, it'd take her a moment to process it all. Her father is... This now? After how she grew up knowing him as a mean, kind of gross and antisocial man? How he was cold even towards her sometimes? After finding out what he did?? And... He's actually loving now? He wants her hugs?? It'd take her a moment to get used to this Scarecrow (I want Dumb!Scarecrow to learn or remember how he thought of Una and how he only showed her affection to manipulate her (mostly), and do his very best to make it up to his baby 🥺🥺🥺🥺🥺)

I can see this AU actually having a better chance at the Rehabilitation AU! I mean, Una was raised with a softer heart for one. But she sees these people as her family. Even if they were so much worse than she expected, she doesn't want to give up on them.

Also not important, but when little Una got used to Scarecrows presence in her life, she showed him a lock of her hair and pointed at the hay sticking out from the seams of his body and basically said they matched 🥺🥺🥺🥺 I know he's a heartless bastard but PLEASE tell me that got to him?? Just a tiny bit????

Una and Lion

She didn't see Lion often, and was scared of his size. Though since he's the friendliest even with his corruption, I don't think it took too long for him and Una to develop an uncle and neice sort of bond. Glinda made sure he didn't eat her, of course. And didn't slip out any information that would be too troubling for the little girl.

Una has many memories of climbing onto Lion, giggling with him and listening to his great tales of the days of old (when he and his friends were still heros). She was always in awe of his great feats of bravery, and he quickly became her favorite storyteller. Yes, even over her father (Lion doesn't insult anybody while telling stories *side eyes Scarecrow*)

Lion sees her as just a little cub 🥺 yes, even now as she's grown up. She's so tiny and bright! Una actually reminds him a little of Dorothy, before everything... He promised her that someday he'd take her to see his great kingdom in the jungle, and that he wouldn't let the monster hurt her (I'm not sure if Lion would know who killed her parents, but either way, he cares about Una to protect her like Dorothy). He doesn't see her often, but when they are both at the palace, it's like old days again when she would crawl all over him. It's a nice break from her conniving family for Una.

I'm not sure if Glinda would let her learn it, but if Una could transform into other animals, she's definitely showing it off to Lion... I'm not sure if that'd be the safest thing to do around the hungry king of beasts, though 😅

Una and Tin

I think it may have taken Una a long time to see Tin. Glinda had to make sure she wouldn't recognize Tin and revert all her progress. It took around a year at least for Glinda to fully trust them meeting.

Little Una was intimidated by Tin Woodmans appearance, not believing at first that that was the same gentle hero her parents told her about. But after seeing Lion, Una approached him and reached for one of his finger blades to hold. Of course, he pulled away, a bit shocked that Glinda had a daughter. But he knew he had to treat her with respect, so he was very polite with the child.

I think that since Tin is too busy being Dorothy's authority and thinking about her, he and Una didn't see each other often. Even less than Lion, maybe? Along with Glinda telling her all about how Tin keeps the peace, Una still sees him as a hero rather than a family member like she does the others. As such, she's very cordial but polite, rather than seeking him out for comfort or loosening up around him.

Of course, they run into each other sometimes when Glinda takes her to the Emerald Palace. The more he sees her, as she gets older, maybe Tin grows more curious about her and asks Scarecrow about her? The two seem to be close, and clearly, Glinda must have big plans for the witch. Perhaps she is meant to help to protect Dorothy??

Una and Dorothy and Ozma/Pete

Una is not too familiar with Dorothy. But she had been excited to meet her. Why wouldn't she want to see the hero and queen of Oz? I'm not sure how much control Glinda has over Dorothy, really, but either way, I don't think Una would like her too much. Dorothy doesn't exactly hide her true colors. Maybe Una accidentally peeved her, and she started screeching at her (maybe Una giggled, and Dorothy took that as her laughing at her). Glinda stepped in however, and took Una aside and told her she needed to be careful around their very stressed ruler. Ever since then, Una has been... Very very conflicted about the witchslayer.

She and Ozma totally gain a sibing bond in this AU! Una was confused about the great fairy being so childish and zoned out, especially hearing that she apparently tried to hurt Dorothy. But she warmed up to the fairy as they got to live and play together. She and Ozma would huddle together when Scarecrow told stories, and they'd have many sleepovers together ^^ as Una grew older, she took it upon herself to care for her new sister, and is hoping to cure her of her memory loss and her supposed corrupted heart.

I think as she gets older and Glinda molds her into the perfect ally more, Una is taken to the palace more. She still retains her good heart though and, despite the servants being afraid of her, she wants to talk to them. Pete was the only one who was willing to approach her, and they would up becoming friends. Una isn't sure why, but something about the boy is familiar. Like she knows him already, somehow. It's strange, though, how he's always disappearing...

Also, I'm considering in this AU, Una might develop a crush on a boy in the palace named Benjamin? I'm not sure, but she wouldn't be so scared of faliing in love here (she doesn't see any risk of losing her lover in the war, unlike her OG self), and I really want to explore her falling in love and how her little family would react to it.

Also, not important, but I found a picrew and made Una! The one on the left is her in the Glinda's Apprentice AU, and the one on the right is Una in the OG timeline (I tried to rough her up as much as possible. Also, this picrew didn't have a silver color for eyes, so they're blue here XD but I promise her eyes are canonically silver. Also, ignore the ears. She has human like ears like her mother, I just liked the art style of this Picrew)
