Later yesterday I had to go into the bedroom for something and when Fric followed me in, I decided to show her the alien in the dogged to see what she’d do. As soon as I picked it up, she became very alert and jumped up on the bed, I assume to get closer to it. When I put it back in the dogbed, she immediate jumped into the dogbed with it and dug the bed up in a circle around it, then jumped out of the bed and went back to the office. To me, this means that the alien is exactly where she wants it to be, she considers Watson’s bed a suitable nest for it (barring any disruptions), and that her responsibility to it doesn’t extend beyond giving it what she considers a good/safe place to sleep.
