She's from the other timeline, the one I wasn't in. That's a little difficult to think about sometimes because being here and having been here there's the knowledge of what I missed, what she probably missed too because our lives have been so entwined in my timeline.
She's told me a bit, I've told her some. We're getting reacquainted I guess, which is the weirdest part but she remembers much of the Agency stuff which means we have shared experiences too.
