Yeah man, I was betting on Aatrox, but they said that "Twice, if I have to." doesn't refer to anyone with an in-game revive mechanic, and RIOT also stated that his enemy is already in the league, so, that leaves us with Hecarim, Karthus and Thresh(Yorick's been confirmed to be out as well...). I think our best guess is Thresh then. Also, it's been said that Thresh will have a new story (I didn't quite understand if they're reworking his lore or what) that tells about a special soul Thresh took away, wich was very similar to the wife he had while in life (*cough* SEN *cough*).
