Well Calleigh is just adorable full stop. She really is so well loved by the team in general. She's always there for the guys and she's not afraid to point out there mistakes. She's just amazing and even though I think Emily is wasted on the show (because of lack of decent lines) but she is really an amazing actress and, like I say so many times, the best thing to have happened to The West Wing after Mary-Louise Parker!
Edit:
And I'm sorry but why is the thought of Emily wet a massive turn-on for me? I'm gay. I think this should be called the Procter-Effect!
