Wow, thank you so much, I'm really glad you enjoyed it. The contradictions are what makes Walter's character so fascinating so I'm really glad they come through. I think the song has a lot of the credit for making that possible. Though John Noble also infuses the character with such depth and charisma it makes the task easy - which is not to take anything away from the other actors too. The shot where he tries to cup Olivia's face and she pulls away is, as yu note, a fantastic microcosm of Walter and Olivia's relationship, so tender and so disturbing simultaneously.

I'm also REALLY GLAD that you like the "catching bullets with our teeth" thing for Olivia because I really feel like it's apt too - that Walter is like some crazy science backup man when Olivia insists on going out there and, well, trying to catch bullets with her teeth (and succeeds).

Thanks so much for the comment! :D
