I was watching some Transformer Prime episodes on youtube. Sometimes people posting comments on episodes say the music or characters remind them of something from Star Wars! Could Silas say "Jack I am your father?" Don't beat me up for having a wild imagination. In Metal Attraction Jack's mother says since Jack's father left. Has Jack or his mother ever seen Silas? Since he has scars, maybe he was injured in the military and required plastic surgery. They might recognize his voice but not his face? Is there anything in the episodes that would rule this out? I don't remember the details of each episode as well as many people here. Just a crazy thought!
