Evil Morty is so freaking smart, he scanned the brains of so many people including Rick freaking Prime, he knows a bunch of shit and has a good amount of experience. Yet he wants to escape the central finite curve and from the looks of things, live on some random fuckass asteroid in the middle of absolutely nowhere in a space mansion.
What is he escaping by leaving the central finite curve? He can’t be controlled, he LITERALLY controlled the citadel as the president for a while. His existence disproves the idea that a Morty can’t beat a Rick. Also, what’s he going to do now? Such a smart fella will get bored living on an asteroid like that, no?
He travels from outside the central finite curve to inside a season AFTER the dinosaurs (claimed to have) stitched up the space wound thing. That should be impossible, no? And yet he did it. What could possibly stand in his way? He can do whatever the heck he wants, no?
