diner, revolving door, and revolver.
There might also be
street, city scene, urban setting, telephone booth, phone booth, call box, telephone box, telephone kiosk, and brasserie.
Basically highlighting both of the relationships with Oliver/Sara and Oliver/Felicty. This video is sort of Sara/Oliver are the past present, and Oliver/Felicity is the present-future. I love both pairings.
