Khal Drogo, it's been awhile. He was once one of Game of Thrones' biggest characters — literally — but then he died. He died in a kind of lame way, though: an infection. Last night on Jimmy Kimmel Live, Jason Momoa, the actor who played him, revealed that though it might've been lame, it was accurate. Though more accurate would be if Drogo died of Daenerys's horse-heart breath.
