i'm still here! i spiraled on picking a face and name and disappeared on you. well that's a really good way to make your second child re-think her entire relationship with her parents and choose to go find her brother. she probably grew up always wanting siblings and never understood why her parents were so standoffish to this idea. surprise! you actually already have a brother! how did he try to contact their parents? i'm wondering if she overheard that whole mess somehow or caught her parents blocking him on facebook or something lol. if he is 28, and she is 23ish she would have been old enough to remember that! i was also thinking they could have common ground about music, mainly emo music? like they both have a natural/genetic inclination towards music and arts. i was thinking of having her have a "fake" life that she shows to her parents where she is studying for the MCAT/med school, but her main passions working with film and her art patreon.
sorry if this is all over the place, i had too many ideas in my head!
