re: Game of Thrones S5:E2:"The House of Black & White", HODORS ONLY (No Readers)

So I was watching S1:E1 tonight cuz I was bored and thought I'd give the series another go around with trying to pay more attention to detail.

Question: how many Stark direwolves are still alive? I know I remember Sansa's getting the axe and I believe a few more of them died as well. I think Jon Snow's is still kicking.

Then I guess for funzies do you think they have any role to play at all or have we moved completely on to bigger creatures like dragons and they're just a forgotten part of the tale. (I suppose other than Bran's who he channels or whatever:: if I remember correctly)
