My friend was telling me about it. The patient was an old man, and he might have had some connection to one the main characters, I think House or Wilson. She wouldn't tell me the ending but it's possible he died. This was a few years ago so it could't have been in the last 2 seasons most likely. I know that's not a lot to go on, but hopefully someone knows. Best answer to the first person to guess, and if no one does, whoever tries hardest!
