Okay so the first 7 minutes is not worth watching. The guy sits afk for multiple rounds and doesn't do anything.

Then on his last round of being AFK Autumn warns him not to spam his mic or he will be banned for 24 hours. I did not see him use his mic once up until that point.

Then Autumn warns him to stop disrespecting her, after he had perhaps used his mic 1-3 times. Nothing can be known of what he said exactly because demos don't record the player's microphone. The first time he used his mic it can be assumed he was answering his teammate's question of "why did you slay me?"

Finally, Dog says he isn't disrespecting her (in chat) and warns her the demo is still rolling.

Autumn proceeds to call him a dumbass and says "why do you think i'm typing? For console."

Then Dog says "you could leave me alone, you know" and Autumn says "Don't talk."

Dog finishes by saying "Don't tell me what to do" and when the demo is completed my assumption is he is kicked.

Take it for what it is worth, but that is what I got from the demo.
