For the real fun, Gabriel should prod someone else from Zagreus' universe about it. It's bound to be more enlightening than anything Zagreus would ever say himself.

Well then. Zagreus looks a little incredulous, but only a little. "I guess I expected Loki to be taller and more northerly." Maybe that only goes for Lokis in some universes. Hang on, does every universe have a Loki? That's gotta be obnoxious for somebody to sort out. "I see why you went with 'Gabriel' instead." He doesn't at all.
