Last night, I was watching the Season 3 episode The Darkling. When I was watching the episode I kept thinking that I liked the Doctor's performance as the alter-ego Doctor, except for the fact that it looked like he was purposefully jutting his lower jaw out during each alter-ego scene. It was like he had an underbite or something and it annoyed me because I didn't understand why Picardo thought it made the alter-ego Doctor look scarier. After the episode, I went on Memory Alpha's page on the Darkling episode and read the following: Did anyone ever know this? I didn't even notice that he wore contact lenses!
