Unless significant military forces come after us, I think we should be fine. I'll talk to Jane about disguises--which will need to be Midgardian for obvious reasons--and safety. But if something does go awry, I will not expect aid or a rescue from New Asgard.
If I didn't think we needed to protect Jane, and I weren't worried about her, I wouldn't suggest it. But if she were to go on her own and something were to happen? Then we have an angry Thor and no way to calm him. I mislike that Thor is so far out of control but keeping Jane safe and as happy as we can is important.
We've got to get him back. Ultimately we may have to strike against the Raft and free him, but if we do we have to be ready to leave Midgard.
