Weren't they supposed to protect him, not shoot him?
Your guess is as good as mine. I still don't know who he was shooting at and why, even after watching it multiple times. I guess that was Bobby looking like a side of raw beef, but why he looked like that, I don't know?
He had what looked like a mask.
No, he was shooting at her, she was trying to get away. It was more of a warming shot.
