The one in this picture looks identical to the Kimblee we knew, but there could still be differences. [She's going to gesture to the priest in the room.] Kirei and I are from the same world, for example, but we remember certain events differently. If he and I are from branching timelines, that naturally means it's true alternate versions of ourselves also exist.

In other words, I was thinking this Kimblee and the one we knew could be an example of that.
