This is one of the few times I honestly have no freaking clue what's going to happen now. I can totally see Brainstorm being a 'Con (especially with the more complicated characters Roberts writes), but I can also see that being a red herring.
Fair points on both (d) and (f)...my thoughts were the emblem on the inside of the facemask was painted by Agent 113 (the Autobot who infiltrated the DJD) so everyone would know who betrayed the Autobots, as previously suggested in this tread (don't remember who suggested that though). The headmaster idea was mostly from the fact that the toy has a headmaster, and I can see Hasbro trying to force that gimmick in there somehow.
Next week. In the meantime, here are some twitter teases: https://twitter.com/jroberts332/status/524353149390577665 https://twitter.com/jroberts332/status/524351647980728321 Eight more days, guys.
