I no longer think it is 'Moonlight'. The plant is upstairs and the computer downstairs so I needed to go up and look closer. There is no red on the stem, the older leaves that are green do have a sort of watermelon pattern and are much lighter than the pictures of 'Moonlight'. PLus, 'Moonlight' is apparently a relatively new hybrid and it's unlikely I'd find that here. I took some more pictures, hopefully someone will recognize it.
