And one person who has always been there for them (whether they knew it or not) is their boss, Assistant Director Walter Skinner (Mitch Pileggi).
One, because Scully is healthy and back to herself, so she can join Mulder in the search for their son.
So it was very shocking to see the two characters throw down in the newly released season 11 trailer with what looks like Skinner making the first move and attacking Mulder.
Skinner has risked his life for their cause time and again, even getting shot in the stomach at one point for his troubles.
