THE GAP. BtVS Intertext/Allusion.
After the destruction of the Hellmouth and Sunnydale at the end of "Chosen," the Scooby Gang assesses the aftermath:
WILLOW: We changed the world. I can feel them, Buffy. All over. Slayers are awakening everywhere.
DAWN: We’ll have to find them.
WILLOW: We will.
GILES: Yes, because the mall was actually in Sunnydale so there’s no hope of going there tomorrow.
DAWN: We destroyed the mall? I fought on the wrong side.
XANDER: All those shops, gone. The Gap, Starbucks, Toy R Us… who will remember all those landmarks unless we tell the world of them?
