The X-Files, Season 1

Mulder:
You got a brother, don't you, Scully?

Scully:
Yeah, I've got an older one and a younger one.

Mulder:
Well, have you ever thought about calling one of them all day long and then all of a sudden the phone rings and it's one of them calling you?

Scully:
Does this pitch somehow end with a way for me to lower my long distance charges?

Mulder:
I believe in psychic connections, and evidence suggests that it's stronger between family members, strongest of all between twin siblings that shared the same womb.

Scully:
OK, maybe. But in this case, one sibling has closer ties to a frozen fudgesicle than he does to his own brother.

Mulder:
Arthur Grable is not dead. He's in a state of consciousness that no human has ever returned from. And what if that state allows one to develop psychic ability to a potential that the conscious mind is too preoccupied to explore or believe in? He could use that ability to control his brother to kill those scientists.
