Derek is an Almighty Janitor. That is, he is completely unremarkable and nobody really cares about him, but Derek is more competent than he lets on.
Subverted: Derek has big problems and fears, but he pushes his problems aside while he focus more on being The Ace, believing that as long as he tries his best, nothing is impossible and like any other human being, no one's perfect.
Double Subverted: ...yet his focus on putting his problems aside merely adds to the growing mental stress, hastening the collapse.
Parodied: Derek is really great at everything because of his many psychological problems: all of his myriad obsessions and quirks and sociopathic tendencies counteract and mix with each other in such as way that he effectively becomes The Ace.
Derek confides in Sara that playing the ace is actually really stressful for him... only to turn around and secretly gloat about how that sob story left her completely wrapped around his little finger. However, it's later implied that he wasn't completely lying about the toll it takes...
That he turned around and gloated to her to cover his tracks, because the thought that someone knows he's not perfect was eating him alive. Turning his moment of weakness into a Sarcastic Confession retroactively.
Defied: As part of his training to become The Ace, Derek was provided with the best psychoanalysts and therapists money could buy.
Discussed: "In the end, any Ace is really just compensating for his own inadequacies."
Conversed: "Wow, the movie's hero's great! He can do anything!" "Just wait: he'll break down from the stress at any moment."
Deconstructed: As it turns out, Derek is a fully capable and effective Hero in his own right, but due to the pressures of society's expectations of larger-than-life supermen — not to mention their assumptions that he must have some hidden inadequacies, since everybody does — he's over-thinking and overworking himself in the quest to become The Ace. Had he just striven for Heroism without trying to live up to the "role" society presented him, he could have excelled.
Reconstructed: Derek knows that his constant need to be the best and live up to high expectations will destroy him, but he pushes forward because his problems are bigger than him and You Can't Fight Fate.
Played For Laughs: Derek's breaking point is finding a single loose thread on one of his expensive suits.
Played For Drama: Thanks to all the pressure to be perfect, Derek's sanity hangs by a thread, and those around him keep unknowingly mashing on his secret Berserk Buttons...
