When Alison gets disoriented, she has to find some small, tangible, happy thing to focus on -- for instance, the stained-glass teddy bear in Katy's porch window. Whenever Serena is looking at a book and sees a picture of two kids, she'll call one of them Serena and the other Alison -- so Mommy Chris reports to Barbara. I just dropped Alison off at Katy, Patrick and Erin's.
