I love the HP fixation having gone deeply into HP with one of my own children (and having even written some HP fanfiction as well). I could totally see Wilson game-fully trying to throw in some Narnia as well.

Nice little bit to explain the Abba ringtone, though it made me sad for Wilson. He lost his biological brother and in a way he lost his chosen brother too. But, the whole Darcy bit made up for it - so very House and Wilson to have House get Wilson to do something that would get him in trouble, but that Wilson would secretly enjoy.
