Lost S4E05 "The Constant"
One of the best episodes yet. Goddamn, it might have been the best. Everything about it was just... wonderful, from beginning to end. Desmond's story is wonderfully fascinating, and Faraday has quickly risen to become one of my favourite characters, and this episode was mainly about those two. So, yeah, it was great. Hope there's more in the vein of this and "Flashes Before Your Eyes."
