Most of this episode is told in flashback because something so horrible has happened that House has finally been dragged in front of a disciplinary hearing. Sure, that happens like four times a year, but this time it’s for serious. Honest. Oh, and it’s because Chase got stabbed partway through. I think it’s probably Chase’s fault, but I wasn’t asked to testify.
The main case is a chemistry teacher who collapsed while jogging. This is why you shouldn’t accidentally cause explosions that break your tumors apart. And Chase also has a case to be diagnosed, but since everyone saw him get stabbed, it’s not as much fun. He’s briefly paralyzed and ends up having to learn to walk again. And he gets an apology from House, so maybe it was all worth it?
