#StarTrek: The Motion Picture - Post credits scene.
Through the recreation deck window, two crew members watch as the new V'Ger lifeform makes it's way out of the Sol system.
Arex strummed gently on his lute. "Where do you think it's going?" he asks. "To seek out new life?"
M'Ress frowns "I'm not sure where it's going. But Spock told me where it's been."
Arex's hands paused over his lute "Oh?"
"During his mind meld with V'Ger, Spock saw that the cloud had passed through the Ceti Alpha system..."
Arex's eyes widened "...do you think..?"
"I don't know what to think" replied M'Ress. "But the sheer size of V'Ger... just being in close proximity could destabilise a planetary system."
Arex paused, and put the lute on the table before him. He suddenly felt he would be unable to sing.
