About this scene
Mall corridor, four separate approach attempts spread across nine minutes. She rejects the first one with a hand wave, the second one with a polite no, the third one with a longer no plus a half-step backwards. The fourth one is different. He waits her out, she's been alone in the same section of the food court for six minutes, and when he comes back this time she doesn't say no. She says give me a second. Then she puts her drink down and walks with him.
What to watch for
Watch the difference between rejection three and the eventual yes. Rejection three has her actually moving away. Six minutes later, when he comes back, she hasn't moved an inch. That's the tell. She wanted to be found again. The yes itself is quiet, no smile, no body language change, just a yeah okay that's somehow more decisive than any of the polite refusals were. White hair, full sentences, eventual yes, on her own terms.
