1. This one can happen sometimes, although not often
2. I explained how I think the weapon switch happened
3. looking above is sometimes just a sign of frustration because he accidentally switched weapons
4. I mean he is under a lot of pressure, everyone is watching him, maybe he was ashamed and panicked. You probably had that too when you were in a clutch and fucked up and panicked a little bit.
