Number 12 is amazing I love him very very very much and Ego Trip is one of my favorite TV movie things ever
I used to experiment with the concept of Dexter and Number 12 Selfcest with Dex being more commanding towards his cowardly-ness. I also had a 12Exe(cutive Mandark) phase

I don't know how or why but you brought back so many memories xdd. Another aspect I like about Number 12 is the implication that Dexter's accent is an affectation and he loses it as he lost his sense of self and confidence, I could go on about it really if you wanted me to
