I would absolutely be down for Five and Caitlyn meeting in the elevator while Cait is having a very good and emotionally stable experience!

And I'm totally canonblind for The Gifted but I'm always happy to have Cait meet new non-posh people. Level III could absolutely be fun for them. Though Cait is so ridiculously self-sacrificing she won't sell him out unless they grab her jaw and physically force her to say the thing.
