Numb3rs Fanfic Finders

I'm looking for fics where Charlie is shown in a less flattering light - focusing on his weaknesses, any of them, really (inability to deal with difficult emotions, egocentrism, extreme focus on the math where everything else suffers etc.) as long as it's causing trouble in his personal relationships (romantic OR family OR friendship). I am *not* looking for flat-out character-bashing, just something that underlines that he isn't an angel.

Any pairing (or none), any rating, any POV, any theme, any length - as long as either you or the author tell me about it ahead.
