Agents Mulder and Scully exchange quips about reports of strange music from the heavens in a clip from tonight's episode of "The X-Files."

The penultimate episode of the miniseries revival, "Babylon" finds Mulder and Scully (David Duchovny and Gillian Anderson) seeking a way to communicate with a comatose bomber in order to prevent a future attack.

The episode also marks the first appearance of the Lone Gunmen (played by Bruce Harwood, Tom Braidwood and Dean Haglund) since their supposed deaths in 2002 during the ninth season. Robbie Amell and Lauren Ambrose also guest star as young FBI agents Miller and Einstein.

"The X-Files" airs tonight at 8 ET/PT on Fox.
