Why Deep and A-Train are still on this show?
They basically have no connection to main plot. And they are not good, not evil. There is no Jaime Lannister redemption role or something for them. They are just two boring, no personality characters that for some reason are still on this show and get so much screen time with their boring non-problems.
Writers dont know what to do with them. So much that they put Deep as some head of some computer department in ep 5 or something. Just because they needed to create some side plot for him.
Just kill them off and introduce new characters.
A-Train is the most useless character in this show. So boring. Just walks around for 3 seasons being miserable and depressed.
