Aziraphale didn't have a chance to respond to Crowley's questions. The demon turned his back to him and rushed off without waiting for an answer. Just like the demon to do that. Things like that got them into trouble- like not verifying a certain child was who they thought it was. Never mind the angel's own similar behavior with a certain flaming sword...
He may not have been verbally invited, but Aziraphale assumed he was. They were together, and that meant they were likely stuck that way until this was resolved. Or they at least got some answers. Or until one of them irritated the other to the point where a separation might be advisable, if only temporary.
As Crowley headed toward his goal, the angel took a look around the room. He'd really not taken the time in the room he'd woken up in, other than the necessary glimpses to know it wasn't familiar. He noted the similar bed and furniture before noticing it.
"Be back in a moment." He flipped the little metal doodad out to keep the door from securing itself and stepped out of the room.
What he had spotted was a basket wrapped in colorful cellophane. Perhaps there was some sort of answer there. More importantly, maybe there was one for him, too. He hurried across the hall into the other room and sure enough, there it was. Whereas Crowley's was wrapped in red plastic wrap, Aziraphales was wrapped in powder blue, but the point was they both had one.
Returning to the room Crowley was in, he held up the basket. "Look. We've both got one. Do you think...?"
Aziraphale thought it was probably just a hospitality basket from the staff, but he didn't see the tell-tale bottles of soap and lotion one might expect. He looked at Crowley, his eyebrows raised. If anything it was a present. Aziraphale liked presents; they were such a show of kindness and generosity it was hard not to.
