Right off the bat, Swift sings in "End Game" about wanting to be with this person forever, which is a common theme in her other songs about Alwyn. The music video also ends in London, which is where Alwyn is from, and has a few Easter eggs about their under-the-radar romance throughout. Swift would explore the idea of being with Alwyn forever in more detail on "Lover," but she lays the seeds of songs like "Lover" and "Paper Rings" on this "Reputation" track. The lyric "I don't wanna miss you / like the other girls do" also echoes other lyrics Swift has about other girls missing out on Alwyn.
