[ He doesn't know mutants, and there wasn't time before to explain it, either. He can assume the missing portions - that the humans in Ruth's world and like Will, and that the mutants are, well, people like her - except that they also still look the same from where Will's standing. But then she also has no eyes...he wonders if there's a price to be paid for her powers, if everyone's like that.

If that's the case, this world dampening her has definitely given her a raw deal, if she can't see.

Will isn't shocked to hear the explanation, in the end. He nods before he remembers that doesn't translate, wincing into a shrug. ] Well, I don't have a gun here. [ Not terribly comforting. It's meant as a joke, even though it's flat. ] And I've got no reason not to trust you. [ Not 'like you', which is different and a lot, but...trust might be even more important, with all of them trapped here. ]

And we were touching the mirror at the same time. It...there's cracks in mine, and probably in yours, I don't know if you touched it yet. They...

The mirrors fixed themselves. And then we were back in the labyrinth together. [ The last word of which is said almost reverently. Will hadn't expected any of that to work, earlier. ]
