This night Röskva didn't sleep in the bathroom, but in the spot under the desk next to my pillow which Alison usually occupies. Alison joined Rustan in my bed (he seems a lot more likely to end up there nowadays, but most often when I'm not in it).
As everyone was tired from the outing, I think she got a full night's rest. At least I wasn't bothered.
In the morning I got out one of the plastic tubes, which I don't leave around if there's high risk of fighting, as it gets rather ugly if someone's trapped in them. Instant success! She hasn't been so happy while here since she discovered where I've got all my boots. Roxane also liked it, but felt it was more expedient to fight Röskva while there was occasion.
