He lets the first bit pass without comment. Some network junk, okay. He might care more if it weren't so minor, but when he has the problems of the past self who was here causing bigger problems, it's hard to worry much over a brief exchange with a version of him she was never close to. He's just glad enough it won't cause more issue.

Besides, the issue of other worlds is much more important, and her combined answer shocks him silent for several moments. Eventually he mutters, "Holy shit," but it takes him a stretch still before he can find something better. "Five? How... how did they work?"

Everything where he came from was linked up somehow. Beforus was just a different Alternia; Earth was part of a universe they made; and Sgrub and Sburb were alternate versions of the same game that they all played on purpose. It was all part of the same reality anyway, on some level, not this... disconnected whatever-it-is he and everyone else have been drawn into. The thought of more places that could yank people out of their home realities isn't unthinkable after this, but it's a shock nonetheless, and not something he naturally considered.
