Oh my god I had entirely forgotten until this moment that Sif was on that one episode of Agents of S.H.I.E.L.D. :') But it would make sense tbh, the stuff they have in Asgard is next level by comparison.

Also, the idea of her showing up with Ragnar and the two of them being terrible distracted students is delightful to me, this definitely must happen.
