Nikki is alastor daughter but Lucifer thinks nikki deserves a better father than alastor

Lucifer sings: Who's been here since day one? I'm truly honored that we've built such a bond (aw) You're like the child that I wish that I had (uh, what?) I care for you, just like a daughter I spawned (hold on now!) It's a little funny, you could almost call me dad

As alastor got pissed off as Lucifer smirk
