* Ardor/Slavetale Sans 'The catalyst' - Depending on how close you two are, Ardor might not care if you two are siblings or not. If they are still taking all of your attention, he will kill your sibling and get over with him. Besides, it’s your own fault for not telling him beforehand. You were supposed to do that, but you never did. Now, drown in the guilt and learn who you are supposed to be with. 

* Roxxy/Slavefell Sans  'The lovable pervert' - Roxxy would be very hurt, but the thing is, he probably wouldn’t be about to kill your sibling, but instead, would have made someone else do that, meaning that that person wouldn’t care if they are your sibling or not. They would still kill your sibling. Oh well, you still had him! No need to be sad.

* Viper/Slaveswap Papyrus 'The skeptical slave' - Honestly, it’s stupid. He won’t kill your sibling, but still. Why didn’t you tell him? You know you almost lost your sibling? He would insult you before telling you to stop being so close, or else, he’ll kill your sibling.

* Wisteria/Slaveswapfell Sans 'The perfectionist' - Wisteria would immediately change his personality into respectful. Of course, he still hated your sibling, but now he needed to follow rules. He will be able to kill your sibling the moment they leave the mansion, but for now, he will play along with the rules, like he always does.

* Pup/Slaveswapfell Papyrus 'The perfect puppy' - Pup would feel like it’s unfair. He doesn’t want someone else to be getting your attention. He knows that he doesn’t deserve your attention, but he still wants it and he’s angry that someone else is getting it. He won’t kill your brother, but he will, for sure, hate your sibling with all he has got.

* Azalea/Slavefellswap Sans 'The housekeeper' - On the surface, Azalea would look silly, saying that he was stupid for being jealous, but in reality, that makes it even worse. It means that you two are really close and he hates that. He would end up killing your sibling, in the most brutal way possible. He can’t forgive anyone who tries to steal you away.

* Foxglove/Slavefellswap Papyrus 'The perfect lover' - Foxglove would be angry, but he would forgive you this one time. He would spare your sibling, but he would make sure the other slaves hate your sibling so your sibling has a horrific time while visiting you, so they would stop visiting you.

* Mortis/SlaveDust Sans 'The loose canon' - Has Mortis ever cared about such things? He brutally murdered his own brother, you think your sibling is someone that he cares about? If he felt like they are in his way, he will kill them and get over with that, without even worrying about it. If you try to stop him, then you will end up dead too.

* Cassiopeia/SlaveOuter Sans 'The perfect prey' - Same as Roxxy, Cassiopeia probably got someone else to kill your sibling before he knew they were your sibling. When he would find out that they were your sibling, he would be mortified, but he wouldn’t tell you about it, just trying to act like he is on your side, even if his guilt would be eating at him.

Being friends with a taken yandere Slavefellswap Sans:

~Honestly, it would be confusing being friends with Azalea while he’s dating the master. You see, you are one of the servants in the household, and one day you just saw him and decided to befriend him.

~It was really hard managing to befriend him, but when you finally did, you felt like you could actually do something to help him a little bit and make his life much better.

~You would think because he’s dating the master, he would have a slightly better life, but that wasn’t the case. It was like the master was only using him for his body and that made you pity him a lot.

~Just please don’t tell him that, alright? That might make you both fight and that wouldn’t be exactly something either of you wants.

~You always give him food from your share and try to help him out with his duties when you aren’t busy. 

~He’s confused about why you keep doing that and it seems like the explanation that he’s your friend doesn’t really work too well for him.

~No matter what, he will slowly open up to you and even tell you that he really desires a little bit more from his relationship with their master.

~You can’t do much for him, and he can’t do much for you but you both support one another like there is no tomorrow and you honestly care for him.

~You make him feel like he can actually be something more than just a slave and he hopes that one day he can escape slavery, and when he does, he will make sure to bring his dear friend with him... *

Dating yandere Slavefellswap Sans:

~Azalea would be very protective of you. You are in a better position than him, but you still aren’t the master. You are one of the servants and even if you have more rights than Azalea could ever dream of, it doesn’t mean that you aren’t in any sort of danger.

~ “Listen to me very closely, my dear lover! This world is truly cruel, and we as the lower ones must fight with all we got to be able to survive...”

~Azalea will try to put a good word on you to the master, trying to get you a better life as much as possible. He will also take all the blame from you just so you could go with your days without trouble, or being fired.

~” Do not even mention, my dear lover. I would even die for you if it meant you being happy”

~If Azalea will see that someone is harassing you, he will convince one of the stronger slaves to come and hurt that person who’s harassing you. You would be surprised how united he and some of the less wanted slaves like Jaws are.

~ “Oh, don’t even mention it, my dear lover. My friend Jaws will always help you out when I can not. Remember that”

~It wouldn’t be a surprise if Azalea actually would let you and Jaws be close, considering that Azalea is a very jealous person.

~ “I just believe you are helping Jaws quite a lot, my dear lover. But do not forget that I am your lover and not him”

~He will probably let you close to his brother too, but much less than Jaws. He knows his brother, and if his brother realizes how great you are, there is no stopping him.

~ “I do not mind you being around Jaws, but do not, under any circumstances, get close to my brother, Foxglove, am I clear, my dear lover?” *

Falling asleep near yandere Slaveouter Sans:

~In all the time that Cassiopeia had worked for you, he had never caught you falling asleep in front of anyone. You were very hard working and you neglected your own health many times for the chance to stay up and actually do more work. Falling asleep on your desk was the last thing he expected you to do.

~” Oh... oh my dear master... how tired you must be...”

~Cassiopeia would make sure to push away anything that could be uncomfortable to your sleep to the side, like papers, pens, and the likes. He would have wanted to carry you back to your room, but he was simply too weak to do so and he wasn’t allowed to use magic.

~” Oh master... how peaceful and beautiful you are...”

~He would probably go and bring you a blanket and pillow so you would be more comfortable, and wouldn’t catch a cold while sleeping on the table.

~ “Please... don’t get sick master... I couldn’t handle that...”

~When he would do every single one of those things, he would finally sit down on the ground, not daring sitting on any furniture and angering you, and simply... staring at you.

~” My master... my beautiful master... so peaceful... mine...”

JEALOUS YANDERE SLAVEOUTER SANS HEADCANONS:

~Cassiopeia would feel like he will lose you if you keep being around that other slave...

~First of all, he would need to understand what Cassiopeia missed that you found in this new slave.

~No matter what Cassiopeia would find out, he would think that you are being seduced by that shameless slave...

~Because of that, he would, without a second thought, try and off this new slave, for trying to take you away.

~You are the only one that treats him like he’s a living being!

~He knows that others want that kindness too, but no one deserved it!

~Cassiopeia’s job was to make sure that no one unworthy was trying to take that care from him...

~After offing the slave, Cassiopeia would try to act the same way as that shameless slave...

~He offed the shameless slave, but it didn’t mean that you wouldn’t go and try to find a replacement for them...

~He would start becoming a lot more touchy, a lot more affection, a lot more needy for your attention...
