I'll start with Phobos as its shorter, but they went back to Amaurot in the time just before the sundering hoping to do a little damage control for Deimos and at least let Emet and Anthea know he was okay and alive still. When getting there though Phobos finds out about the future and Emet's end, and that hurt to know that their brother essentially lets his grief be the end of him. However, because no one knew Phobos was even a thing Hydaelyn told them that they're the unknown factor so maybe they do something to change the future, maybe they don't. Hearing this Phobos continues on with the intention of pretending to be Deimos if it became to late because maybe Emet didn't see his brother and that's what led him down this path of grief. Easy to do since they look like Deimos save for their personal style and eyes. When the sundering happens and Phobos ends up being the one to push the unsundered into the rift they speak to Emet as if they are Deimos and as far as Emet knew that was his brother who's last act was to save him and express how he has faith in Emet to lead the people onward to a better tomorrow. It is a very short moment but one that feels needs to be said, as Phobos would much rather let themselves be forgotten or never known if it means helping more people.

Sib's whole start of story is her running away from home to a place where no one knows who she is, and she intends to keep it that way as much as she can. So in an effort to keep her high born status under further secrecy she changed how she dressed, her hair color, and even her accent, along with opting to never disclose her last name. She wants to be known for who she is behind the title and she does a damn good job of it with only a few people knowing for sure who she is (Minfilia, Thancred, Urianger, Y'shtola, Lyse, Count Edmont, and Aymeric, Estinien and Alphie after HW), until you get to EW and she kind of has to let it be known. Even books of the future that G'raha read never made mention of her Lady status.

Its imperative to her to have some kind of outside identity as she doesn't know who she is outside of being a Lady and she knows there has to be someone there she just can't find her and she definitely won't find her if everyone treats her a certain way because of her status or she gets ratted out to her parents because her mom was offering up a nice reward for bringing Sib home. The goal was attained, she finds who she is and is all the better for it.

How people find out though at different times of the story are as follows:

The og Scions (Minfilia, Thancred, Y'shtola, Urianger, Lyse, Tataru, and Papalymo) know because her mother sent a letter asking for their help in locating her as a hail mary i am determined to find my daughter one way or another kind of deal. While it's not made a priority, they keep a general eye out, with Thancred finding her and letting Minfilia know. By that time though Hydaelyn was letting it be known to Minfilia that Sib needed to stay with them and not go back home, so she wasn't sent away and didn't make it a deal to acknowledge it.

Alphie, Count Edmont, Aymeric, Haurchefaunt, and Estinien find out because Count Edmont thought her face familiar looking, which it was because there were posters making their way among some high society with Sib's face (yes her mother went overboard) and really put time into confirming Sib's identity when he saw her and Haurchefaunt get close because it would ensure a higher status for his son that couldn't ever really be more than a bastard. Basically knowing that her parents would grant him that title of Lord more officially and so he sent a letter inquiring to her mother on if there were any engagements or anything Sib ran away from and to make arrangements to wed the two. It did lead to conversations with Aymeric about it, and it was during a dinner that it was brought up around Alphie and he found out that way. Alphie though didn't want to believe it because she certainly didn't act like her title and that's his friend, she surely would tell him. After more thought he understood, and frankly kicked himself a little for not figuring it out sooner since there were obvious signs the entire time. Estinien found out because once finding out that Sib had befriended Aymeric her mother sent the man....so many letters asking him to take her daughter's hand in marriage. Estinien heard the grumbling from Aymeric and took some time out from his travels to go to Thavnair and attempt to strong arm Sib's mother into stopping her letter writing (it didn't last long).

By EW Krile finds out a bit first because Sib didn't want to make waves right away in Sharlayan so she tried to switch out paperwork so it had the correct information on who she was to save the hassle of "Why did you lie on your identification?" that probably would have ensued. By the time you get to Thavnair and its after the Tower of Zot when you get the boxes of talismans that everyone else that wasn't in on it finds out, because her mother was not letting her daughter leave Thavnair without seeing her parents and so she held a box hostage to make her come to dinner. Gig was up she had to tell them all that yes she's a Lady and she had been the whole time, she just never thought they'd ever end up in Thavnair so didn't say anything. Ali still has a hard time believing it until getting to her house and its kind of hard not to believe it at that point. Raha was thoroughly confused as to how that information was never recorded anywhere or that no one else put the two together. Demos also feels a little bamboozled cause he should have known and its like the one thing he kept missing in his observations with her. Everyone thought that man was in on it from the start but he wasn't and kept accidently turning a blind eye to it all.
