para-amour:

”The X-Files’ upcoming season may finally see Mulder (David Duchovny) and Scully (Gillian Anderson) reconnect with their long-lost son William. But will this family reunion lead to a romantic reunion between the beloved believer and skeptic? It’s not out of the question.
 
Anderson tells TV Guide that the search for William will bring Mulder and Scully “closer together,” although she acknowledges that Scully is much more passionate about finding him. But while Mulder isn’t as invested in finding his son, he remains devoted to being a much-needed support system for Scully throughout this trying mission.
 
Will all this be enough to re-spark the romance between the pair? We sure hope so, seeing as Anderson has stated this will likely be her final turn as Dana Scully. And can you really imagine The X-Files ending without them getting back together? No, us neither.”
