"I think I'll be fine." He turns to flash a smile at her, which turns out quite a bit sharper than he intended. "Thanks anyway." Maybe she really does know, and she's just toying with him. That'd fit in with all the other time-travelers he's ever known.

His attempt at being tricky in his approach means they're heading back towards where he ditched the phone, and towards the bar where all of this started in the first place. At least they don't know him by name there. None of that really matters anyway now that she's got his photo, but it's something. Maybe. He picks up his pace as they reach a crosswalk, taking long quick strides. If he bolts now, he breaks his (possibly already broken) cover for sure. If she keeps tailing him for too long, the same result. How can he shake her?
