[The topic shift takes him by surprise and, for a moment, he isn't sure what to say. Tessa left the City, presumably to go back to her own universe, almost three years ago. No one has ever asked him about her because everyone he knew then left, as well. If he wasn't so uncertain, it might occur to him that it could be awkward to share this with someone who shares Tessa's face.]
Theresa Gray. I knew her in the City, and she left it a long long before I did. I loved her. [That was easy enough to say. There had been a time when remembering Tessa was painful, but distance has made it easier to recall everything that had been good.] She looked like you. This sounds insane, I realize that, but people from different universes sometimes have the same faces.
[There's someone with his face running around Marina as he speaks. That look-alike is slightly younger and quite reclusive, so it hasn't been as unsettling as he would have expected.]
