Q&A with Hugh Howey discussion

Hugh, maybe this is a stupid question, but in your short story on your blog "While You are greater than Myself, reduce Myself", the last line references Charles, the nurse-bot, saying: "Charles considered, briefly, doing the same." Unless I'm missing something, this seems out of place, since Charles wasn't mentioned as being in the room in the latter half of the story. Is this a typo? Should it be Daniel instead?
