"I am trying to understand you," Castiel said honestly, looking at Gadreel. He was powerful, definitely more powerful than him. Right now perhaps even more powerful than Lucifer, whose grace appeared to be depleted. Probably another reason he was not going up against Lazar directly himself. "I have done terrible things for reasons no one but me understood at the time."

So maybe him and Gadreel were alike. Lucifer glanced from Castiel to Gadreel, deciding that he wanted to nip that conversation in the bud. "He's just easily distracted, that's all. Piss off with your Greater Good 101 class, Castiel."

"Lazar has become more powerful by using Raphael." That was what Sam was putting together here. "A powerful Prince of Hell. Sure. Why not toss that to us? All in a day's work."

Lucifer hissed, but looked amused. "Ah, Sammy, Sammy, Sammy. Every time I meet you, you're more and more bitter. Sooner or later you'll be so sick of it all you can't stand it any more. Make sure to keep me on speed dial for that time."

"Fuck off. Never." Sam shook his head, unsure what to even deal with first here. "How are you out? Where's Aleister? Did you kill him?"

"Think you got all the info I'm willing to give already. Now go be good hunters, yeah? Raphael needs you."
