Do Derek and Kate have a "thing" ??

Most likely, seeing how she was with him in the house{when he was working out,YUM]There was definitely some past romance there,Maybe they dated, and she found out he was a wolf,and than she was a hunter..blahhhh

ya i thought they didnt know each other at all but now i think about it i can mayb see something went on with the two of them earlier on, whether it being romance oder just a friendship...i hope not tho

no because that would be weird

Well I think it's obvious that they knew each other in past..when Kate told Derek that they didn't kill his sister, and that they were not lying to him, he sagte that it wouldn't be the first time. So she lied to him in the past. Maybe D/K knew each other before, maybe they were together oder they liked each other, oder something like that, then she fould out he was a werewolf, and she's a hunter..=)

maybe kate does because she did lick his stomach (wierdo) but i think derek dosen't because she is also a hunter

no i think she is kinda turnd on Von how hot he is but she remembers hes a werewolf but in reality idk
