There are only two episodes of the six-episode limited revival series left of "The X-Files," and the next episode is introducing two new faces, and three very familiar ones.

As previously reported, "The Flash's" Robbie Amell and "Six Feet Under's" Lauren Ambrose will be guest starring on next week's "X-Files" episode called "Babylon." EW has the first clip of Amell and Ambrose meeting Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson.) Strangely enough Amell and Duchovny are both obsessed with the paranormal, and Ambrose and Anderson's characters are skeptical medical doctors. Are Ambrose and Amell to future Mulder and Scully?

While the clip does not feature returning fan favorites, The Lone Gunemen, EW also shared the first official photo of the trio, which can be seen below. The Lone Gunmen -- Bruce Harwood, Tom Braidwood, and Dean Haglund -- were killed off in season nine of "The X-Files," but series creator Chris Carter promises to bring them back in a way that suits the story without having to resurrect the dead.

Check out the clip below, and be sure to catch "The X-Files" Monday at 8 p.m. on Fox.
