does toi think Katherine is just messing with Damon and does care about him?

Yeah!!!!!........i think she actually care about him.....atleast a bit.....i mean.not plus than she likes stefan.....but, i think she likes damon too:)

I think at first no, she was just using him, but now since watching 2x16 the last aired episode where he rejected her when she tried to come on to him, seeing that I kinda put a spark in Kathrine, like a 'oh i can get toi if i want' I think him telling her no, and that he doesn't want her will make her want him, if that makes sense. She realize that she does have some kind of feelings for him before it's over with but I look for Damon to be the one to kill her.
