New Game of Thrones teaser released

So many questions, so many half answers.

Why is Tyrion in chains and saying, rather glibly, before a court: "the only thing I'm guilty of is being a dwarf"?

Why is his brother, Jaime Lannister, the only person being nice to him?

Who is the devishly handsome Red Viper? And did he learn his moves from watching the Matrix?

How good is Arya Stark getting with that sword? 

How big is that dragon? And how are they going to top the brutal red wedding in the last Game of Thrones series?

Only one thing is sure: winter is still coming... boom.
