The sad ending......... Spoilerized since it may make some people unhappy. Completely made up in my mind. Spoiler They end up in a new timeline. Carter was never sheriff, nor has he ever been to Eureka because he and his daughter never drove through it (pilot episode). He's in a marriage to someone who isn't an intellectual snob, or alone still. Allison is married to Stark, and Stark is still head of GD. They're living in Eureka with their daughter and her son. Jack's daughter is doing hard time, as that seemed like her original path before coming to Eureka. Jo is sheriff and with Taggart (I always found their relationship creepy, but what evas). Fargo and Holly are together and happy in Eureka. Zane is at GD, but more under house arrest, monitored by none other than Beverly, who reports to Senator Wen. Henry is dead from the artifact, He died saving Kim from season 1. Kim is with Parrish (Wesley Crusher). Oh wait, that would be a horrible ending!!!! Why did I kill Henry off? At the end of Season 1, four years in the future from that present Carter went back in time to save the world, but in the process wiped out that future. In that future he and Allison were happily married. Only Jack and Henry had memories of the now collapsed future timeline. Henry erased Carters memories (without Carter's permission), which seemed to be out of spite as Henry was angry that Carter had to sacrifice Kim to save the world. Ever since then I have never really trusted Henry and thought he couldn't be trusted, other than the fact everyone trusts him, and he and Jack are like best friends, even though he stole 4 years of happy memories from Jack.
