Ellen. One of Scully's best friends.

Ellen was one of Special Agent Dana Scully's best friends.  So close that Scully had been made godmother to Ellen's son Trent


Scully attended her godson Trent's birthday party and spent much of her time there speaking with her friend Ellen.  They discussed Fox Mulder with Ellen suggesting that maybe Scully liked Mulder.  Scully started to say that Mulder was a jerk but ultimately settled on the idea that he was obsessed with his work. 

When one of the fathers of the kids at the party showed up to take his son, Ellen pointed out to Scully that he was divorced when she noticed her interest in the man.
