But there were parts of every hospital that House hated, and that were the waiting areas.

The "that" in there stuck out to me - doesn't sound right. I think maybe it should be "those"?

Anyway. I really liked this. I don't know if I buy Wilson getting let off suicide watch early...I thought suicide watch was taken pretty seriously. But I love that Wilson won't say what, if anything, he saw...so it's all still a mystery.
