I was going to evaluate which of the ot3 had what. but then I realized they each had all three
parker- competent (notoriously best thief in the world), confident (doesn't care what anyone else thinks, she knows she's the best), and character (autism creature with a heart of gold. orphan turned thief. learning to like things, become a better person and understand people better)
hardison- competent (probably best hacker in the world), confident (sometimes a little too ballsy, but he's usually warranted so we let it pass), character (that's literally all he is. geeky black foster kid who loves his nana, is a family man, and loves his partners)
eliot- competent (best hitter out there. literally good at everything he does which would be annoying as a trope if he wasn't so put-upon every time he has to do something), confidence (absolutely), character (outdated sad boi hitman man trope but also loves family, respects women, and mentally adopts every child he sees)
