"Don't mind me.. I'm just..uh..Doing work."
Derek is by no means a normal person. He likes to be outgoing and goofy and sometimes a little crazy. But there are certain people who will get him to shut up. He can be shy and quiet one second but loud and obnoxious another. He doesn't take too kindly to ignorance and tends to ignore anyone who stinks of it. Derek isn't one to walk away from a problem either. He will stand and face whatever he's dealing with and solve it. He acts this same way towards his job. Derek always has to finish one task before going to another, and will sometimes ignore everyone else just so he doesn't get distracted. He can be a bit stubborn at times, and once he's made up his mind there's no changing it. But he is open to reason, even if most of the time all he does is shut it out and go his own way.
