@Chezka: Cool, that works. Alex would have initially thought her pranking and gibes were genuinely mean-spirited -- but it would've been pointed out to her soon enough that she isn't, by the bar owner or someone. Every time she teases her, she has to consciously remind herself that she's not serious -- often resulting in forced and very nervous laughter. Otherwise, she admires Izzie's people skills, and enjoys her constant energy. She hopes to learn a thing or two from her.

Rosemary: Unlike Izzie, Alex isn't as fond of Rosemary because she believes that her sardonic gibes are out of a genuine wish to hurt her -- whether she actually does or not. She constantly fears that she's misunderstanding the woman somehow, due to her lack of overt expression and use of sarcasm. Therefore, she's constantly on alert when Rosemary is around in hopes of not accidentally misconstruing her -- which Alex finds to be quite stressful.

Shall work on rest of relationships in my CS.

EDIT: Nice IC posts, guys. I'll get one up sometime today.
