The urge to laugh wells up within Aziraphale as he watches the cogs of Crowley's brain turn, futilely trying to spit out the answer to a question he likely never asked. Rather than laughing, he rests his head against Crowley's face and waits patiently to see if Crowley might work it out for himself.

Unsurprisingly, he doesn't.

"Strategy and philosophy," Aziraphale answers helpfully. He's at least moderately well versed on the topic, not that it has thus really served to any interest. It hadn't made him any more fond of them and he was less interested in them than he was in Yggdrasil as a whole. "And you mean Sigyn."

Whom of which was a rather odd choice to be on this pantheon. She was a barely known figure, wasn't she? Known more as Loki's wife than anyone of any true importance or aspect. "They don't exactly correspond with the mythology as I have always known it, but I suppose it would be pointless to start splitting hairs," he mentions, a little off-handedly.
