scathach is very careful about her body language; she rarely gives anything away by it. interestingly, almost everything she reads off other people is interpreted as some kind of threat. anyway, she usually stands perfectly still, not breathing, not blinking. she tries to take in as much around her with as little distraction as possible.

gemma is pretty easy to read. she flinches and blushes easily. it's easy to tell when she's mad because her brow will immediately furrow and her lips purse. she has a pretty good poker face when she knows she needs one, but if she's caught off guard she's basically a book. she isn't very good at reading people around her.

rikku is so active with her body language. she waggles her hands when she's excited, she flinches back with her whole body when disgusted, she jumps up and down when she's happy. reading her is the easiest thing. she can read those around her, decently.

molly is decent about body language. she herself is an open book, but she can read people rather well, both physically and emotionally. her power is empathy for a reason. she really has trouble hiding facial expressions, especially.

nill is the master of body language, and nobody can convince me otherwise. she can't talk. she communicates with her body: hear hands, her expressions, her movements. each twitch is indicative of something. she's pretty good at reading others as well.
