Can I just take a moment to appreciate the lighting/colours in all the House episodes that aren't the Pilot?
Because seriously, what is this?
I'm not saying that I'm an expert or anything, every time we have a lighting class at the university I'm left just as confused as I was (well, almost), but the colouring in this episode makes me thing they've all got some illness or skin disease or something. And Wilson's hair almost looked gray-ish at one point.
