The X-Files, Season 1

Scully:
Do me a favor, Mulder. Let me say it. Reincarnation.

Mulder:
Metempsychosis, transmigration, reimbodiment, call it what you will.

Scully:
All based on the coincidence that Michelle Bishop and Officer Morris both practice the obscure art of paper folding?

Mulder:
Well, what about the composite drawing and the dolls and the fact that Michelle was witness to two deaths that can be tied to Charlie Morris?

Scully:
So what, you think he's back like Peter Proud to avenge his murder?

Mulder:
It's not so far-fetched, Scully. Reincarnation is a basic tenet of many major religions.

Scully:
That still doesn't explain how an eight-year-old girl can kill two grown men.

Mulder:
Well, individuals with strong past-life memories often exhibit enhanced psychic abilities - ESP, telekinesis.

Scully:
So where does that leave us?

Mulder:
One short step away from proving the pre-existence of the human soul.
