Evil Morty in “Unfinished Business”

You sellout Mortys kill me. I'd hate you more than the Ricks you worship if there was any point. But you can't help it. You were bred for it. Wanna see?

You already know rogue Ricks used Mortys to hide themselves from the Citadel. But you might not know it works so well that the Citadel became its own Morty market. And I'm sure you don't know how far they've gone to help supply meet demand. Sure, Ricks could scour infinity for naturally occurring grandsons, but why bother? So much work. Such an admission of need. There aren't "infinite versions" of our grandfather, Morty – he's an infinite smear of one shitty old man. And he's attached to us infinitely through his weakness and our forgiveness. This is why we're with him... this is why we're alive.
