Okay so, given the SB spot, we can speculate the female voice over is a creator,(this can be backed by the female mo-cap actress seen on set alongside Mark and crew), asking if Prime seeks redemption from them. So we've speculated Prime is acting the way he is out of dark energon, mind control, or some space plague. But the vibe I and many others got from this spot was that him doing for the good of the creators is his own choice. I speculate that, since it's said he Spoiler discovers a dead Cybertron and blames himself , hes going to return to earth to find whatever it is to revive Cybertron but on the way he meets this female creator and she somehow manipulates him to fall for a trap in which maybe she ends up mind controlling him. So it would be half his choice and half hers.
