'House' recap: You're Risking a Doctor's Life!
But the real drama comes from House, alone in a burning building with a corpse, talking to figments of his imagination that include Kutner, Cameron, and Stacy. We never learn just how the building caught on fire, but it probably has something to do with House being out of his mind on heroin. Anyway, he burns to death and there are some very touching eulogies.
And then he's not really dead, so he and Wilson go and ride motorcycles for a few months until Wilson presumably dies. The end!
