So I was reading through "Episode Ideas", "Characters that should come back", and "Shawn's Talents", and this popped into my head:
Abigail goes to the police because she's being stalked by a former student (she's a teacher, right?). Anyway, she and Shawn immediatly hit it off again, he gets put on her case, and they end up getting close. Juliet gives him a hard time and confronts him about getting personally involved with a client (she is a little too upset over this). Shawn nabs the stalker but it shakes Abigail up, as she is not used to dealing with this sort of thing on a regular basis they way Shawn is. Abigail and Shawn go their separate ways at the end, and Shawn and Juliet both realize that Juliet cares more about Shawn than she thought, or is willing to admit.
Oh, and this would be a great way to bring up Shawn's shooting skills that we haven't seen since the pilot. I can't really see him hurting someone seriously, much less killing anyone, but maybe someone is holding a gun an Abigail or something and he shoots them through the hand.
If you were going to pitch an episode, what would the summary be?
