It makes sense that characters from different Syfy universes could actually exist together. This time, Fargo from 'Eureka' visits the warehouse to give it a computer update. With Fargo (Neil Grayston) at the helm instead of tech-savvy Claudia (Allison Scagliotti), we just knew something was going to go wrong.

Instead of booting up properly, the warehouse's system detected a catastrophic failure setting off a protective program called Hugo One. Of course, it took Artie's (Saul Rubinek) extensive history with the warehouse to figure out that it was a projection of the original computer programmer Hugo Miller (Rene Auburjonois) who unfortunately went crazy. While Claudia, Fargo, and Artie tried to avoid the adapting intelligence of Hugo One, Pete (Eddie McClintock) and Myka (Joanne Kelly) went to find the real one at the sanitarium.

The real Hugo unfortunately really did have mental issues. Although he dropped hints about spinning and dancing, the wily Hugo led Pete and Myka around like a child who could not focus.

While looking for a solution, Artie, Claudia, and Fargo used Babel stone allowing them to hide any plans from Hugo One who initiated protective protocols. Unfortunately for Claudia and Fargo, one of the protocols was initiating Fargo's spider bots to try and stop them from exploring the warehouse.

Avoiding the spiders, they did manage to find Woerheimer's Zoetrope that showed Claudia Fargo's background and thoughts when spun. But to try and fight the spider bots, Fargo finally came up with brilliant plan to use Ben Franklin's ring to enhance his laser gun. In his coolest moment, Fargo defeated the bots as the laser became very much like a light saber.

Artie used his brilliance to figure out that Hugo used the zoetrope to transfer a part of himself to the computer, and that Hugo One was actually that part. Playing and cheating at Battleship allowed him to trick Hugo One to let Pete and Myka bring in the real Hugo to reverse the process.

Finally, the computer system was fixed. Before Fargo left, he did show his affection for the clever Claudia. However, her attraction to Todd meant that Fargo left with only a promise of friendship. Unfortunately for her, Todd (Nolan Gerard Funk) broke her heart, but maybe it opened the door for Fargo.

In the end, it was a successful crossover with lots of nerd references. It also sets up any of the audience who watches both shows to watch the next 'Eureka' episode to see Claudia visit Fargo.

What Worked

Using Fargo as the crossover character was a brilliant decision. He and Claudia are doppelgangers except that one is almost always successful and the other causes chaos. Because of the expectation for Fargo to mess something up, it created a fun game of trying to figure out what he would touch that would go wrong.

Throwing a crossover character also furthered the development of Claudia's character. Her exploration into having a relationship outside of the warehouse makes her more complex. Having Fargo be a potential love interest makes his visit even better.

The cherry on top was seeing Rene Auburjonois make a return to sci-fi television. With quality guest stars, the show's potential will continue to grow.

What Didnt Work

Knowing that the show has only an hour to do things wasn't enough to allow for more chaos to follow Fargo. He was almost a little bit too successful at the warehouse. But if that's the only fault to find in the episode, it's extremely minor.

Those who watch both shows should tune in to see Claudia visit Eureka.
