I got the feeling from back in KLG that she might have cheated on Zak. There was a line about Kara being drunk and all over some major. I don't know if that was supposed to be when she was with Zak, or after his death. If it was when she was with Zak, then that should be a huge wake-up call for Lee. If she cheats on her fiancee(your brother) and then cheats on her husband(a guy who really loves her), hello, Lee, she's going to cheat on you too.

If this huge love for Lee *puke* couldn't keep her from falling in love/lust with Sam and marrying him, then it isn't going to keep her from straying either. Makes me want to choke a bitch too.
