None of the episodes has nothing to do wth Unexlained Files but Doom & Gloom, how we and the earth are going to be destroyed, from giant artificial robots to Super Novas radiation bursts to the suns solar flares wiping out the earth's atmosphere, giant asteroids, giant comet's, giant metors, alien diseases and all the astronomers say, it's going to happen, it's going to happen sooner or later and they all sound so happy so when it does happen they can say I told you, but they won't be able to because they will be dead also. Unexplained Files, I'd say it has been explained pretty good. I don't know if this contains any spoilers, just my opinion.
