Season 7 episode 5, when we see some Evil Morty backstory, there's an exact moment you see him switch from a scared little kid to someone who has their shit together. I think his personality as a Morty is fabricated as a way of self preservation. He needs to act anxious and angry and submissive yet defiant in order to keep himself from being killed. We see later in this flashback segment Evil Morty deleting his folder from the Morty Adoption Agency files. His photo is different from the others, in that he looks profoundly fed up. He has the typical Evil Morty face despite this being from before he got that nickname. To me, all this says is that Evil Morty has always been 'like that'. However the particular moment we see in S7Ep5 was just that little thing that pushed him over the edge. That simple goading from Rick is what gets him. I think that shows alot about what he had been through already that he was so near the brink, he dropped his whole facade at a mere "Oh yes he is, Oh no he's not".

Just posting this even though I don't like it

Em is trying to adjust his portal gun. Prime is whining about his lover (who hates him). Neither are in a good mood.

Don't mind how weird this looks I was so tired making it :-( usually I put more effort into my interdimensional hypehouse art but i got bored of this one fast

Prime was originally meant to be leaning on the table but standing up however I've decided he's sitting now and leaning over into Evil Mortys personal space (dramatically).
