Haha! I'm not too sure that Jin will be slipping into that one night stand spot :P  She would feel far too guilty about Wyatt (even if she's too chicken to do anything about it), to have a one night fling.  That girl sure does love to flirt and play though, but she'd not take it anywhere beyond that unless she wanted to get serious with someone, or she was just too sexually frustrated to abstain.  ::)
