The mid-season finale of SyFy’s Eureka will be on tonight and our beloved cast will be experiencing a bit of déjà vu from the fourth season opener. Check out the synopsis, teaser, and sneak peek of the season closer, “I’ll Be Seeing You”, below. James Callis, please stop inadvertently destroying the world! (Just kidding, we love it when you try!)

Synopsis for Eureka Finale for First Half of Season 4, “I’ll Be Seeing You”

After the bridge device disappears, Carter (Colin Ferguson), Jo (Erica Cerra), Fargo (Neil Grayston) and Allison (Salli Richardson-Whitfield) find themselves in a déjà vu situation as their investigation puts Trevor Grant (James Callis) right at the top of the suspect list. The proverbial noose around his neck only tightens when they discover evidence that connects him to Beverly Barlowe (Debrah Farentino), and her motive will put at risk everything they have struggled to achieve.

The fourth season of Eureka is comprised of twenty episodes. This mid-season closer puts us at episode nine of twenty. The tenth episode will be a stand-alone Christmas episode and then the “back-ten” will air sometime after that.

In case you missed any of this fourth season, SyFy will be airing a Eureka marathon proceeding the mid-season finale, so set your DVRs, people! SyFy will begin with the last few episodes of season three and then every episode of season four up to the mid-season finale.
