It was too short a breakup for my taste, but I didn't think the series had the courage to stretch it out for a year. They really are co-dependents, aren't they? Or at least co-enablers. Actually, I don't think House wants a best friend so much as he wants someone around to applaud...
Something I'm becoming very curious about: how much pain is House actually in? There's virtually no way to measure agony on a real scale: all we know is that he's capable of some degree of function when he's off the Vicodin -- and he once deliberately broke his hand to distract himself from the pain.
