As a somewhat irrelevant point, producer Paul Davids has said that the series writers were aware of the Matrix of Leadership before the movie hit, with its "Oh, hey. I have this in me now." I don't know how it got along to Furman and Budiansky, for the life of me. I may be off in my timing with the premiere of the Creation Matrix and the debut of the ill-fated movie, but I doubt it.
That was an honestly good episode, I thought. Not a hint of the deus ex ma-key-na, and we got some decent interaction between Sentinel and Optimus. The "We don't know what you eat" moment was worth a snicker (if only because it was a case of the cartoon sayin' what I was thinkin'), and it only took a throw-away bit involving Headmaster's arrest to really solidify Powell as a future threat. Moar character episodes plz... N00b.
I don't know if you've caught up with season two so far, Thad, but it outright opened with Ultra Magnus, Sentinel Prime, and Jazz landing. The Decepticons are still on the back-burner for now, with Starscream understandably M.I.A. (this is a trend for him in this continuity), and Megs is setting his sights on Cybertron. So really, the Ultra Magnus/Optimus Prime dynamic is still a possibility. I'll probably keep watching this cartoon even if you stop, Thad, but it'd be a shame to lose your informed counter-points. No pressure, though; it's your half-hour.
