Warehouse 13 Crossovers
In August 2010, Eureka crossed over with fellow Syfy series Warehouse 13. In the Warehouse 13 episode "13.1", Fargo is contacted by Mrs. Frederic to update the Warehouse's antiquated computer system. While there, he spends extensive time with their resident teenage tech genius, Claudia Donovan, during which he develops a crush on her. He asks Claudia if he can get a tour of the Warehouse, to which Claudia says he doesn't have the clearance level; however, when the computer system goes haywire, he is forced to take refuge in the Warehouse with Claudia and Artie. He seems hopeful of a potential relationship with Claudia, particularly when she tells him that she wishes she had a guy like him in her life that she did not have to lie to about her job. After she kisses Fargo, however, she explains that she had been thinking of her boyfriend, Todd. Fargo is visibly put off by this.
In Eureka's "Crossing Over," Claudia comes to Eureka to check out the town and Global Dynamics. Upon being asked, she tells Fargo that she and Todd broke up. Soon after, they find themselves in the middle of a minefield with Claudia lying on top of Fargo. Carter eventually comes along to save them both from the mines by defusing them. Though they kiss multiple times in both crossover episodes and they have an undeniable attraction to each other, Fargo and Claudia's relationship status is currently unknown. Complicating this potential relationship, Claudia connects romantically with Todd in a later Warehouse 13 episode, but Todd is immediately taken away by his witness protection handlers. Further complicating the relationship is the fact that Fargo becomes involved with Dr. Holly Marten (Felicia Day) in later episodes of Eureka.
Fargo returned to Warehouse 13 in July 2011 in "Don't Hate the Player". It is revealed that one of his side projects was working on a virtual reality gaming system called "Fargames" with two game programmers from Palo Alto. However, the human brain wouldn't process the virtual information to Fargo's liking, so he managed to track down an Artifact to stimulate the brain into accepting the signal. When things predictably go wrong, Fargo and one of the programmers get trapped in the game, and the other programmer reveals Fargo told him to call Claudia if anything went wrong, resulting in a Warehouse investigation. It's discovered that the game Fargo is playing is called "Fortress 13", which is based on his adventure in the Warehouse the previous year. Even though Doug is currently trying to woo Holly Marten, he models the princess in his game after Claudia.
