I just found something very interesting. Remember when Caesar asked one of the slaves to shave his beard, and Crassus' slave tells him "Dominus wants you unshaven"? Well look at the new trailer for Episode 3 at 0:02 http://www.youtube.com/watch?v=jy5t9...l_pCyxEk07EIRw
You see that dude in the white shorts with Blonde hair? I think that's Caesar. I think he's infiltrating the rebels. That's why Crassus wanted him unshaven and long hair. Now look at "The Rebels" preview http://www.youtube.com/watch?v=xf2pW...l_pCyxEk07EIRw. Look at 0:50 where Crixus and Spartacus are fighting. Look who is in the background. Caesar.
