a fun episode to watch with a light yet clearly written plot line. but more then the crime plot, i loved watching the bits and pieces of scenes that are completely unrelated to the crime (like when castle points outs esposito's donuts frosting). I like how there's a story within the story that brings out each of their personality.
the bit about kate's "number" was particularly interesting. Are they already in a relationship and just don't know it yet?
