Talk about can of whoopass
Peter giving the observer a palm-heal strike was a la Neo for sure. Wasn't expecting the neck breaking though. Is it the implant or is Peter just that fucking pissed they killed his daughter. Not sure I'm comfortable with that level of revenge for his character.
And is Walter slipping back to the person he was before the took out parts of his brain? He must have been a real asshole, more like the "Walternate".
Looks like Peter and Walter are on the road to becoming less human. My wife is even getting a little creeped out with the way things are going.
