my read on it was that basically all of season one was setting up for foggy/karen and matt/claire but also karen has a crush on matt that isn't reciprocated (honestly i don't think it's a love-crush i think it's more infatuation or s/t) but (as far as i read it) this changes with that last hand-holding scene in episode 13 because it kinda looked/felt not-quite-romantic but also not-quite-platonic. (also my take on foggy sleeping with marci is that it was more a i'm-very-sad-and-quite-drunk sort of comfort thing, not necessarily a i'm-still-in-love-with-you thing.)

personally (having never read the comics/having no background info on daredevil at all) i liked matt/claire (she's so real with him i love her) and i really like foggy/karen but i don't dig the inter-office romance thing.
