House
5x21 Saviors
5x22 House Divided
The first episode here is nothing to write home about, but the second was brilliant, the return of a familiar face -- though in an unusual way -- making for an excellent twist that works magnificently. The only downside is some poor CGI, the opening shot to Saviors looking no better than a bad computer game and the fire in House Divided having all the reality of a child's painting. That said, it did make for a hilarious scene in the morgue -- not something you see very often. Except in House.

Wetter than a rainstorm on a river with a wet blanket floating down it.
