It looks like Lyra and Iorek have switched places.  Like Lyra used to do, Iorek is sitting hunched in a ball with gooey eyes and breathing through his mouth.
Much unlike her former self, Lyra is sitting up, looking around and trying to play fight with Iorek.  She is activly playing alone and with toys.  Mum says we might take Iorek back to the vets next weekend.
