so i got a question, i was watching transformers tonight, and towards the end, right after sam kills megatron, optimus prime says to megatron as he dies, "You left me no choice, brother" so... this brings up a very interesting question. is optimus prime referring to him as a brother, like an old comrade? or is he referring to him as an actual "brother"? I'm sure no one hear knows the correct answer. but do you guys think it's possible that Optimus prime and megatron ARE brothers? i only say this, because i know there has been "brothers" in the past in transformers, so is bay trying to say that they are related? that would make an interesting story/plot in the next movie. so what do you guys think?
