Derek Morgan (Shemar Moore) and Penelope Garcia (Kirsten Vangsness) in Criminal Minds are two of the closest friends on the BAU, and the stars have clear chemistry — so much so that many viewers wonder if Moore and Vangsness friends in real life. Criminal Minds followed the FBI's Behavioural Analysis Unit, and the ensemble cast is part of what has made the show so beloved. Derek is one of the longest-tenured members of the series. He is gruff the muscle of the BAU, but has a platonic soft spot for Penelope Garcia.
