Lightbearer DLC Edit
Kitty is encountered at the music shop where she works, immediately after getting excited to see Nick at the shop her husband, Richard Bates, pops up and interrupts her from her from speaking to Nick. On the piano Nick will find a note that reveals that Kitty is planning to leave Richard for Nick.
Later in the game Nick wakes up to find her lying next to him, albeit dead.
- She accidentally calls Nick "Lick Nightbearer" before correcting herself and saying "Barenighter", this was presumably done so her husband wouldn't know Lightbearer was in the shop, which he realizes anyways.
