I just want to see Old Man Zuko trolling the fuck out of the genocidal, narcissistic, self loathing (not mutually exclusive) ball of daddy issues that is post Avengers MCU Loki. He'd be like "guys guys guys, I'm not even going to take him out of his cell, unlike some people." *glares at Thor* "I'm just going to give him some tea. And misery." Because after a lifetime Ozai and Azula, he's used to it.
