Eureka: Season 1, Episode 12

1 - 12: Once in a Lifetime

Nathan Stark is given the opportunity to investigate "the Artifact." After it is tested (with Kim's help), we cut to 2010 and Eureka is a very different place. Stark is a billionaire in California, Henry is married to Kim as well as the principal of Tesla High school and the head of Global Dynamics. Carter and Allison are married, and Allison is pregnant. Zoe is the valedictorian of her class, which is graduating that day. Jo and Taggart are dating. But soon problems start to appear all over town: things that the town has experienced in the past 4 years start to happen again, a tornado nearly destroying half of downtown Eureka. Also, a body is found in Section 5, near the Artifact. They test it and find that the body belongs to Kim Deacon, Henry's wife. Henry explains that back in 2006, during Stark's test on the Artifact, Kim was extracting a sample when an explosion occurred, killing her. Henry then used Walter Perkins's tachyon accelerator to go back in time and stop her from dying. This new timeline caused all of the anomalies. The past must be fixed. Stark comes to town to help with the tachyon accelerator. Carter goes back to 2006 and stops Henry from saving Kim in the explosion. The timeline is fixed. We also learn that Beverly had implanted a chip in Nathan's neck so that the Consortium can gain second-hand access to the Artifact.
