As you can see Villain decided to get a tag team partner, LuckyOne was able to recover and they tag teamed to eliminate Victim, and then me, but they were both eliminated by Anothervictim on same pot. I tried to tell Villain that what he did is not cool but he just gave me the middle finger. I was also going to limp in with my rags to help eliminate LuckyOne but Villain has been very aggressive and I dont want to spew my chips.

I tried to complain to Pokerstars about this incident but they said, this is the first time they played together so its not collusion, whatever, I put some notes on this player and will get my revenge, bwahahahahahahaha.
