The Doctor at his best tries to fix Rick and Morty
Personally the episode were Rick and Morty jump to another dimension after the love potion Rick made morty help screw up the whole planet ruined the show for me, to me Rick should have known better and should have tried fix his home world instead of abandoning it. I can't get into the show as much, I feel terrible for Summer at the end of it too. It's too messed up seeing him act like the other versions of his family he found are the same people as the originals, like nothing happned-- they're not the same people and that's the end of it.
The Doctor is sent back in time to before Rick made the love potion by me and is tasked with doing these things: Passing judgement on Rick for abandoning his home world and family except Morty after using a machine I gave him to show Rick what he did and what happened as a result, he can kill him in this situation, but only after he gets answers out of him about what's going on in his head about the whole matter and why he did it. Fixing Jerry's life. Fixing morty's life. And fixing summers life.
