Gamma discussions

I was wondering if any of you were able to clear up something I was confused about. Mainly, what part of Alpha is Gary or Gamma? I didn’t hear any reference to it before. The only things I remember Gamma doing is telling knock knock jokes and monitoring a download of a file one time with epsilon and Carolina. He doesn’t seem to represent a trait to me. Maybe deception? But then why would the Alpha need to split of its deception? Also, how was Gamma like 10,000 years in the past when Church got blown back in time? It makes it seem like Gamma is a different entity kinda. Gary has always seemed off to me (he is also the only one who has a name other than its assigned name). Perhaps I missed something?
