Fan: Combine Commando


Billy is vary different from today's Billy, he has matured from today's videos. His mental illness where he thinks he is a 3 year old has almost been cured, but still in him (A little bit). Billy is a mature 20 year old that has a dark side (when he tries to kill an inncoent Combine Soldier) and a good loving side (When he gave mercy to that Combine soldier and hugged his long lost Sister). He has a naive view on the combine (He hates what they do, but understands why they do it). He still has little outbursts sometimes of his old self.
