Full Frontal Nerdity/WMG

Shawn has been uploaded to the Internet.

 * While he was clearly human at some point in time, the webcam is often treated as if it were his only physical form, particularly during the arc where he tried to turn it into a robot. We've never seen him in person, and we have no proof of (and not much indication of) his actually residing in Alaska. We do know he can connect to the Internet, so that indicates some sort of "cyber ghost.
 * When they played the Doctor Who RPG, he called being forced to play K-9 racial profiling. Perhaps this has some merit.

Shawn is a woman.

 * We have never seen Shawn, and neither has most of the cast. Her real name is Shawna. They either just assume that Shawn has a really high voice or she intentionally keeps it low.
 * You know, "Shawn" can be a female name...
