The Doctor wanders around the steel-and-glass shopping centre. The 51st century is very clinical in its architecture, and he's not sure he likes it. Feels too sterile.
Amy has dragged Rory off to do some shopping, but the Doctor has managed to escape her evil plan to buy him something other than suspenders and stripes.
Shoving his hands into his pockets, the Doctor strolls among the patrons and shops, wrinkling his nose at the displays. Fashions really are the oddest things. They should try bow ties. Bow ties are cool.
He turns his head from side to side, watching the people more than the windows. It's because of this that he spots her, only a few feet away, her characteristic mess of sandy-brown curls bobbing up and down with her steps.
Sure enough, she turns.
He jogs up to her.
"River, it's me."
She stares at him blankly, studying him.
"Do I know you?"
With a jolt, the Doctor realizes that she doesn't recognize him. It's too early in her time line. This is their first meeting.
His grin grows very wide. This is his one chance, and he doesn't plan on wasting it.
"Hello, Sweetie," he says.
