5 Nita is more about accepting responsibility than blame, necessarily. Though she can still absolutely take it on when she doesn't need to (hello, Survivor's Guilt!)
21 Iiii have to assume the answer is yes; in canon, we rarely see her having to deal with both school life and errantry and/or aliens at the same time. Wizardry itself yes, phrased as a culture clash, not so much. In fic/RP, Nita does tend to draw lines in terms of 'friends I do [X] with, friends I do [Y] with', both with peers and adults.
25 Nita can absolutely get uncomfortable with surprise/upfront flattery and come-ons. She may be polite about it (especially if they're peers/both wizards), but she does not like it, and will complain about that behavior with people she trusts.
3 Nita is overconfident in being able to solve problems if she just focuses/works hard enough at it - she knows she has to put in work, and that all spells will work if not necessarily in the way a wizard intends , but anything she does having no effect whatsoever can either unnerve or anger her, depending on why whatever she tried didn't work.
She is also underconfident in her visionary talent - she's been training it, trying her best to understand her visions, but almost by definition she can't control her visions, and everything she sees is itself influenced by her/her moods/what she lets herself see and understand.
6 So Nita grew up dealing with bullying! This is something she knows has influenced her - her initial tendency in canon being to minimize her impact, and her 'knowing' that her speaking up tends to get her in trouble whether she's right or not. Learning how to break the cycle and disassociate speaking up from bad things happening was part of her Ordeal,
She's less aware of this coloring her social tendencies in new situations - not wizardry, but the Barge for certain; when there's so much history that she can only barely touch, it's hard to tell what will be a hot-button issue, what problems have been solved already, or if people will respond consistently when problems are pointed out.
14 ... I know I could play her as being more of an older sibling type, but with an age distribution like TLV's, it's far less likely to happen short of a Breach. She does have a habit of sibling-ing people who are closer to her in age/experience, but this is mostly seen in canon and in a small number of previous games I had her in.
ALSO (since it came up in another plurk) to go back to 6 - there's definite parentification tendencies, more because Nita feels she has to assume them - but her sister and dad are also aware of what's happening (post- her mother's death), so while they're struggling together, they do what they can to share the load.
