Aw man...haven't been this gutted about a death since they killed off soap in call of duty modern warfare!
Any articles I've read seem to suggest he is 100% dead. Kit talking about when they wrapped his final scene, for example.
Seems such a waste to build him up so much. Honestly the red wedding is one thing, but this feels like too much, like they're doing it for just shock value, alright we get it, you kill off whoever you want. But this is just one too far I feel. It doesn't have the same shock, it just feels like 'wtf did they do that for'
