The official synopsis for My Struggle reads as follows:

Fox Mulder (David duchovny) and Dana Scully (Gillian Anderson) have been approached by Tad O'Malley (guest star Joel Mchale), a popular conspiracy theorist web TV show host, who believes he has uncovered a significant government conspiracy. With the assistance of FBI Assistant Director Walter Skinner (Mitch Pileggi), O'Malley seeks to enlist the help of former X-Files agents Mulder and Scully, who have since severed ties with the FBI. Through O'Malley, they are introduced to Sveta (guest star Annett Mahendru), a possible alien abductee who shares shocking information with them that will challenge everything that Mulder has ever believed about the existence of aliens and the US government's role in covering them up.

The official synopsis for Founder's Mutation reads as follows:

When a scientist suddenly commits suicide, Mulder and Scully investigate what unseen force may have driven him to it. What they uncover is a laboratory where extreme genetic experimentation has been going on for decades, breeding subjects who possess unexpected and dangerous powers – and who harbor deep resentments.

Actor David Duchovny also spoke about Mulder and Scully's relationship shift. He told The Hollywood Reporter, "We're not bickering while we're running with our guns out. The relationship was never played [before this]. It was never… the predominant aspect of the show as written. It was something that was unspoken. I think it remains that way. I personally don't want to Mulder and Scully sitting in couples' therapy; that's not what the show is. You can find that on other shows."
