I don't know the timeline, but something happened in there, and something also happened outside. There was reportedly blood near the garden, and something like slime.

[ Wereoctopus slime is his thought, but of course he couldn't find anything when he looked around the garden. ]

I think it took off his arm down here, and chased him upstairs and outside. And then... he came back to the hall where Luna and I were asleep, for whatever reason.

[ To find Luna, he's hoping, to get help. ]
