  • Mitchell rarely ever watches Grimm. "I just don't need to see it...I like to think about things from the's more fun if you play pretend all the way, which means that you're not watching yourself play pretend. You're inside the imaginary reality... If you're looking at yourself, you're not allowing yourself to be completely immersed..." He also compares watching Grimm to hearing the sound of his own voice and will only watch if he's really interested to see what the director of a particular episode did.[1]
  • Silas, likely a short form of the name Silvanus, is a Roman name derived from Latin that means "wood, forest."[2]
