Thor stops scratching Goose. He wants to ask what she means by now, but before he can, Carol starts going off about some kind of page.

"What kind of page?" he asks carefully. It's possible that they might not be from the same timeline; there was already a Skrull here who was most decidedly not from his timeline, and a few others who knew or knew of an alternate version of him.

He hopes for Carol's sake that she isn't from the same reality he is.
