Blunson welcomes House to Ward 6, then soon after escorts him to the isolation ward when he breaks the rules, noting that it didn't take long. Later, he leads him to isolation for the second time. He's also the one who keeps locking the piano when someone forgets to do it.
Later, he helps break up the staged fight between House and Alvie.
In the end, Blunson is the person who gets the music box to give to Annie Bohm.
