It's no secret that "The Flash's" Robbie Amell will be guest starring on an upcoming episode of "The X-Files." In fact, his casting has made speculation about the six-episode event series very intriguing.

The mystery surrounding his character stems from the possibility that he and Lauren Ambrose could be Mulder and Scully 2.0. Amell plays Agent Miller, an FBI agent who is obsessed with the paranormal. Ambrose plays Agent Einstein, Miller's partner and a medical doctor. Sound familiar?

With questions surrounding the revival series, and theories about a potential spin off, it would appear that Amell and Ambrose could be the right pair to take over for David Duchovny and Gillian Anderson after this season is over.

Will Mulder and Scully pass the X-Files torch to these new agents? Check out the trailer for the upcoming episode "Babylon," which airs Monday February 15, at 8 p.m. on Fox.
