the first quote is a joke. he was claiming to be 3cp0 and was the whole time until he was caught. everyone knows this, he never actually seriously claiming to be chewbacca.
he said you were the bounty hunter, he also said you were the SK. I also think you're the SK. get over it, you're counter accusations aren't going to get you anywhere, you're nontown and a thread to town no matter how you try to spin it. yes you killed nov, but you also killed docblue on night 1. you're not going to continue being helpful and need to be lynched.
