Aside from his own world's Lucifer, Balthazar is as close to fallen as any of his world's angels. They're all celestial, but perhaps that means none of them are celestial in quite the same way as Lucifer's band. Either way, Balthazar himself has demonstrated an almost complete indifference to whether an angel is Fallen or not. He understands Lucifer's perspective, at least a little, but status of that nature is almost a moot point to him.

"No, no...the point would be to stop the war, not participate in it." His hand finds Lucifer's, and he laces their fingers together idly. "I think if Raphael agrees to an armistice, Castiel will lay down arms, too. You're right, though. We don't want him here. He sent Virgil after me before, and I handled that, but even if he didn't come through himself, if he wanted to send angels to cause trouble, he could."

Mind you, he's a little pleased with himself at how well he neutralized Virgil--without killing or even wounding him, although given the subsequent rampage, a case could be made that he should have been more aggressive. "I think the first thing to do would be to collect a few angels from my world that I know I can trust. As backup. Aziraphale wants to meet a Cupid anyway."

He breaks into a grin and looks up at Lucifer. "So, come to my world to visit and help me select artwork for a gallery show with a theme of romantic love? It can double as a mini engagement party. The humans that work for me there won't know anything but that you're my fiance. And I'll take you all around Chicago on dates for however long we can spend there."

"You deserve a vacation, inasmuch as you can have one."
