The character in the last panel is Alice, the main character of Nowhere University, and Shada's character based on herself.  The dragon Alice is holding is one she drew with the magic pencil a few storylines ago (it was last mentioned in Crossover Strip #2, and the actual event happened here).  Daria is Shada's counterpart in my strip, and Alice is Shada's counterpart in hers, so we had fun imagining what their reactions to each other would be.  ^_^
