So… Does Starscream know about Unicron?
I mean, he wasn’t around when the season 1 finale took place. There was nobody who could tell him about the whole ‘Yeah, planet’s core is a chaos god’ thing. And I don’t think anybody’s really had the chance or inclination to sit down and tell him about it. As far as I can tell, all Starscream knows about the incident is that shortly after ditching the Decepticons the weather got really fucked up one day.
I find the idea of him being clueless to all this both amusing and sad.
