I started watching it again, and the one line I don't think anyone mentioned was Shawn's to Juliet right after Shawn's face was under The Mantis mask.
Shawn: I know, you know I'm not telling the truth. I know, you know.
I mean, how sneaky can you get letting that line in? Sorry, but it made me laugh.
I'm all for superheroes!
Which is why I'm watching this ep and writing one where Shawn is psychic. Well, continuing it, anyway.
