Pretty weirded out tbh. If I took him straight from canon he'd probably do the same thing Ginger is doing and just kind of laugh it off and pretend that it's not confusing him a whole bunch and kind of awkward in a bizarre, multiverse-bending way, but at this point he'd be tempted to grill her about it--and it would start out as casual gossip, sadly. You and your snowbeau kept each other warm, eh Ginger?? Eh???

And then it gets weird.
