There's a long moment of silence that passes - and even just a few seconds wasted is generally too many for Odin's taste. But a long, long moment passes without so much as blinking or breathing before the god says flatly, "All of this -" suspicion, accusation, conspiracy, anger, frustration; a mortal risking the permanent erasure of their being simply to prove a point, "- has been over the matter of a difference in time period?"

The Allfather isn't angry. He's just disappointed. And then he disappears as quickly as he'd arrived, leaving Crowley behind in his place looking by all outward appearances exactly as he had before he disappeared. They can figure the rest out themselves.
