LOL, I don't know why you're acting pissy with me. Initially you said he was "flailing" his arms around which appears to be the exact opposite of what's happening and in fact made me think I was missing what happened (when in fact I initially assumed the posturing was part of it).The "doing something with his arms by his side" is him pretending to be a gorilla. You did see it. It's there. If you need the additional context clues mentioned to get you to 100% that's fine but it's there.
As I posted on the main boards, I don't know why people are pretending it's not there.
I'm not "pretending" like it's not there. Moving on.
