"Ah!" The Doctor grabs for her, just barely scooping her up before she hits the ground. It also means that in doing so he drops the small glass trinket he was futzing with and breaks it. "Oh shoot!" He winces, glances at the shopkeeper while still wincing, "Sorry, I. I'll pay for that still." He wasn't actually going to buy it originally. Oh well.

He looks over at Kaldur, smiling quickly. "It's okay. I know how it is. It's awfully easy to get lost in this city. Don't worry."
