Final Timeline

Having saved time by sacrificing himself, there is technically no James Cole. The Cole from the preceding timelines is saved by being splintered into an alternate timeline where the show's events did not occur and he does not really exist. He and Cassie live happily here. The Jones' are alive and united. Etc.
