Crowley pulls off his sunglasses to get a better look over the edge of the booth. Hastur is creating fire, tossing it left and right. Causing chaos. Causing destruction. Basically, being a Very Good Demon. Even if he isn't acting on orders, he'll get an accommodation for this.

He looks back at Aziraphale. There's a chance---a very good chance---that Hastur will kill Crowley out there. This could be it. This could be the last time they see each other. This could be the last time he looks at his angel, the last time he sees him. But Aziraphale will escape, he tells himself. Aziraphale will live through this, and that's all that matters.

"I'll meet you at the temple," he says. "I'll be there."

He could tell him he loves him, right now. He could tell him that, but even now it's hard. Even now, there are so many things between them.
