This is an episode that I remember being really blown away by as a kid because it was one of the first I ever saw and at the time it was always one of the more haunting and emotional stories, I was genuinely disturbed by the death of Ricky in the prologue. I don't find it as great now but it's still a very good well-developed story and a fairly mature one for this show, as in its own way it deals with the death of a kid and the survivor's guilt of his friend. I still have a fondness for it and get why it's a fan favourite, it's a very touching episode. I must say though that I think what they're trying to sell at the opening campfire scene when the adorably unibrowed David is trying to say some junk about how someone stealing your bike is like taking a part of your brain or whatever, just pretty ridiculous, you can't do 'bike lore!' I like how it's one of those tales where there is no evil or supernatural threat involved to anyone, although you don't get that until well into the story when it's revealed that the spectre of Ricky hasn't come back to haunt Mike because he's angry that he couldn't save him, but only to warn him that his little brother Ben is in danger so that he'll be able to rescue him from a similar sad fate. And it's poignant when Mike finally sees his old friend face-to-face and touches his arm and says "cold", not "cool!" The part where Mike's in the classroom and sees Ricky felt a bit like a little homage to a scene from "A Nightmare on Elm Street" to me. So Ricky was more of an angel than a ghost, it's a poignant tale. I always found it kind of eerie the way the shiny red bicycle became a rusty brown one and you learn post-tale that the remains of Ricky were finally found, because his spirit could at last rest in peace now that his task was done. Still a mightily effective tale, do treasure your friends while you can, and thank you show runners for a real series classic!
