I agree with La entirely.
I love Faye, and I haven't been able to stand Dora ever since she kissed Martin. To me, the Dora-Martin relationship is sort of like those movies where the guy can't get the girl he wants, settles for another one, and then the second one turns out to be crazy/evil/a man, and then he goes back to the first girl, who he belongs with. I've been waiting for a breakup of some sort since it happened, and since it's really affecting Faye's character (as in the whole "Faye = comic relief" thing), it bothers me even more.
So... Love Faye, don't like Dora. Well, I DO like Dora sometimes, but not as a couple with Martin. She's an interesting character, but... Not with Martin.
Plus, there was a comic a few days ago where she was wanting Faye to get laid, and Faye says she's not that type of girl. I kind of wanted Faye to punch her for that.
I want to point out that no, I don't totally hate Dora. I like her sometimes. Just not when she's being couple-y with Martin or making fun of Faye.
