Rick and Morty
S2E4: Total Rickall
Cousin Nicky was a parasite?!
Six, Morty! There's supposed to be six of us!
lfthere's seven, then that means somebody's not real.
But how did you know it was Nicky?
I guessed. That's why I aimed for his shoulder.
So we can't trust any of our memories now?
Nicky was the reason we found that old Nazi submarine.
Did that not even happen?
Well, of course it happened.
