One of the most important things with formulaic dramas is keeping it fresh, and the writers manage to do this with most episodes. This one was fantastic in the way the patient was diagnosed quite quickly, but then House had to find a heart for him.
I thought the dead womans husband, played by Heroe's Greg Grunberg, was absolutely fantastic, and gave a great scope to the episode. House's determination (or obsession, depending on the semantic you want to use) was clear in his determination to cure his patient- one whom he seemed to quite like, judgeing by their brief scenes together.
The one liners were once again spot on in this episode. It is always amusing to watch House at work, but a lot of it depends on Hugh Lauries timing, as well as the great timing of the rest of the cast, in particular Robert Sean Leonard. The scenes between House and Wilson were yet again brilliant, and with the added twist of Wilson's marriage falling apart.
The clinic scene was fanatastic again, although he was pretty screwed up!
Overall, the Season keeps on delivery cracking episode after cracking episode. I must be getting repetetive...Oh dear! =)
