I feel the same way about Miles/Gregor, but I thought I'd try you on it because I've seen more almost-UST between them in your fic than anywhere else ;-). Oddly, while Miles/Ivan would seem impossibly incestuous to me (not that that stops fandom, but it would bother me), Miles/Gregor doesn't feel quite like that even though they are foster-brothers and raised together.

Alicia/Kalinda - well, I feel that Kalinda has quite a crush on Alicia, but the extent to which Alicia reciprocates that ... well, she's good at keeping her cards close to her chest.

And for all that he deserves it, I can't help liking Peter a lot more than Will.
