It wasn't a weird sight to see both Lucifer and Alastor having a heated argument between them, as they always want to proove that they're better than the other... You didn't expect that this time they'd have beef with eachother about who'd be a better father figure for you though.

Lucifer: “I'm the goddamn ruler of Hell! I can give nikki anything she want! You can't top that!”

Alastor: “That means nothing if you go absent because of your punny obsession with rubber ducks.”
