I enjoyed the episode and the 'trip' down House's memory lane. I was surprised though that I got the Amber clue so much sooner than he did. After all even when he has concussion I can hardly keep up to the speed of thought inside House's brain. Maybe I understood the meaning of the necklace because I am a fan of Diana Gabaldon (second book in her Outlander series is called "A Dragonfly in Amber"). I can't help but wonder if the writer knew this.
House exams the necklace in his living room an asks
House: "What is that, a mosquito?"
Mystery woman answers.
woman: Maybe just a fly.
