MULDER'S FATHER?

I'm still confused about who is Fox Mulder's father? Was it really Bill Mulder or Cigarette-Smoking Man? Also, would Mulder and Scully have access to their weapons in future or would they be reinstated to the FBI? As most of the magazine articles are still articulating that it's a story of two FBI agents.

I'm reluctant to try answering any more questions from memory, but my recollection is that -- while it appears the Cigarette-Smoking Man believed he was Mulder's biological father -- the series never definitively answered the question one way or another.
As for whether Mulder and Scully are reinstated at the FBI in the new movie... you'll have to wait and see!
