That quote is from Eric Foreman from that episode, my favorite one. He's telling a couple how dangerous the treatment could be, but that it's worth the risk.
Things I really like about this episode: The characters have more 'real' chemistry together, although they only have done the pilot together, you can really get a sense of the camradery between the actors.
What is really great about the earlier episodes of House is how much time is spent in the clinic. You can really see the sarcasm come through, and Dr. House's humor is really awesome in this episode. The scenes with Dr. Cuddy and House are so-so, but overall, I would still give this particular episode a 9/10.
