After the end of each music video, Swift makes sure to thank every person who starred in it and worked on the set and her collaborators. In this particula r end-credit scene, fans noticed a nod to another song on Red called "Starlight."
"And to all our families who supported us as we dream impossible things," the last line of the credits reads. The lyrics in the corresponding song go, "Don't you see the starlight, starlight? Don't you dream impossible things?" Whether this is a reference to another video or just to the song, it got fans talking.
