You're saying nothing happens, and yet a major major character just died. I'm going to disagree with you there.
Apart from that one major thing that happened absolutely nothing else has happened (that happened in the 2nd episode and we are now already on the 5th). The pacing is definitely off compared to the first two seasons. I felt this drag since last season though. But i think it has something to do with having so much characters and sub plots that you never really give enough focus to one.
