Yes, she is “like Lestat’s adopted daughter or something.” That’s probably the best description of her!

^She looks smtg like this: Flora and the Zephyrs [detail] by John William Waterhouse. [X]
My headcanon for kid!Rose:

^This smile, this is what Uncle Lestan would do just about anything for! Perform whole soliloquys while doing handstands, pretend the floor is lava, make silly noises, funny faces, anything. ❤ (This has nothing to do w/ her being Tom Cruise’s daughter; really! Physically, she’s my kid!Rose headcanon)
Spoilers ahead.
I don’t remember her childhood story too well, tagging @roselioncourt for that, but I think it was a rough childhood before she was rescued? I pictured her as unhealthfully slender during that time. Lestat rescued her and brought her to live with her new parental figures (two ladies, her “Aunts,” not sure whether they were also romantically involved w/ each other), and he checked in on her every so often, paid for everything, bc he is a philanthropist and loves kids.
Rose knew him as “Uncle Lestan” until her crappy professor boyfriend informed her of the VC, and exploded at her w/ an unnecessary amount of rage bc he thought she was making it up that she considered Lestat to not only be TOTES REAL but basically her loving benefactor! HOW DARE SHE SUUGEST SUCH A THING. Why couldn’t she just be a sexual object for her possessive boyfriend, and only speak to agree with or flatter him?? HOW DARE SHE be a person with her own life and backstory?? Pffft. <– sarcasm.
ANYWAY she and Lestat’s biological son end up growing close for shared connection to Lestat, and bc our series needed a het YA Twilight couple apparently. Eventually she becomes Lestat’s “real” daughter when her Dark Gift reception is poor and he has to step in and perform it properly bc of course he had to do it himself, “if you want smtg done right, gotta do it yourself.”
