[At least while Billy's looking so flustered, Jane clocks Loki's immediate departure as a pretty solid sign that, well. He just pulled a Loki thing. She doesn't know what this Loki would call them, but Thor always just called them "Loki things" when he told her stories.

Taking Billy's hand, she shakes it gently. Technically she's not actively powered right now, but after a few too many mishaps Jane's figured out that it's better to just be careful all the time, even when she doesn't have super strength.]

I have... no idea who you are, I'm so sorry, but it's great to meet you! I have found out that Lokis are the same no matter what universe they come from, though, so. No worries.

[Honestly, the fact that there's so many of them also feels like a Loki Thing™ but she doesn't have enough information to make that call.]
