As a previous Sparkplug slash bunny made me think, the really interesting part would be studying how the Autobots would react to human opinions of homosexuality in the 1980s

...I think that one was mine. Autobots confused about why the human media is so disturbed by Sparkplug having a male lover?

how would it affect Perceptor, finding out he was reprogrammed by the Autobots, now that his creation is the Autobots leader?

Especially if the programming is undone. Poor Percy's responsible for his enemies(?) continued survival as a faction.
