Please, i want to know your thoughts about something. That scene at Jane's house, we could hear someone screaming "Wait! No!" and then a "Shot". WHAT THE HELL happened at Jane's house? 

For what i could understand, or that was the concussion bomb that knocked everybody out, or Heller did another shit job not explaining who was shoted and why. Ok, McAllister put the frozen body at the scene after Jane and the other suspects were unconcious, and then leave the scene with that black car, that im just wondering, WHERE THE HELL he got that car?? If it was really him, of course. 

I know there is not really an answer to that, since Heller didnt explain, but what do you think?
