So I watched, I think, all of warehouse 13 a little while ago. Like more than a year but I can’t remember how long ago. Pretty sure I got to the end. Been watching eureka lately and woa. Episode with someone from warehouse13. Thing is there may have been a crossover episode in warehouse13 but since I did not know eureka I may not have recognized it.
There’s two crossovers on the warehouse 13 side, Fargo and Claudia kiss before her boyfriend moves away and the the gang save Fargo and his room mates from Beatrix potter’s magic teapot. There are several references too.
