Mulder: Who are these people who can just murder with impunity and we can't do anything about it?
Skinner: Let it go, Agent Mulder.
Mulder: Like hell.
Skinner: There's nothing you can do.
Mulder: What can you do about it?
Skinner: There's only one thing I can do, Agent Mulder. As of right now, I'm reopening the X-Files. That's what they fear the most.
