Rhea is sort of...
It's sort of difficult to explain but I will attempt it.
I've never really elaborated on how her potential works before, so I'll start with that first.
Every time she hears a lie, she gets a sharp burst of pain in her head. It kind of sucks. She can tune it out by concentrating (otherwise, she wouldn't be able to get through plays!) and it doesn't work if she isn't near the other person (so it's fine for her to watch tv or talk to peeps through the blogs) but it is. it is painful.
Now, she's had this from birth - and. Because everyone she's known as a child has lied to her in some way (Santa, the Easter bunny, boys have cooties so you can't date 'til you're forty, the usual stuff you get fed as a child) and she's picked up on every lie anyone in her vicinity has told, she. has some problems with associating people with pain.
She's also not very good with the social stuff. People = pain and thus she is pretty happy to ignore most of them! But then. She didn't know that she was the only person who could tell people were lying which led to awkward outbursts like "What are you doing?! Why are you still with him you know he's lying about loving you!" or "-hey, wait, why are you letting off you know his homework didn't really get eaten by the dog!" which lead to most people her own age (and indeed, older) just. avoiding her - or worse, bullying her because of it. But spending time at Countshire has really helped with the socialising problem - while she initially reacted in a pretty hostile way to people, she's gotten. Well, she'll never be that great as far as socialising is concerned, but she is better than she was and speedily improving.
Another problem she has is trust. She does not trust people, and inside she is very bitter about it (even if I fail at playing it). The way she sees it, if they're willing to do stuff like jerk people around by lying to them, the things that must go on in their heads that she can't see must be absolutely horrible. Deep down, she's afraid of humans, and kind of. Abhors human contact, but at the same time, kind of craves it. A-and I kind of mean that physically as well as emotionally - she's always been very isolated, and I doubt her parents have ever done things like hug her or hold her hand much and since she's never had the chance to do that sort of thing with friends (never. having had friends before) when people try to hug her or get into her personal space she kind of goes "fghjk NO OUT", even if hugging is what she needs. People close to her, feel free to hug her anyway. She likes it, even if it makes her go "fghjkl".
fffffff THIS IS TOO LONG ALREADY FOR ME TO EXPAND ON HER CR as much as I'd love to. Ask me in the comments if you want my view on her view of your character.
As far as Rhea needing things to do. I don't mind - she's shockingly good at rolling with whatever is thrown her way. If it's too bad, she kind of retreats back into her ":|" shell for protection. Maybe...someone could find out about her relationship with her parents? Or maybe idk help work out the trust issues she has (<-note: I would really like some help solving these just because I like her being happy).
Or her apathy issues idk Rhea is one great big grab-bag of issues.
