Donna's out doing some early Christmas shopping, and the person she'd been shopping for turning up out of the darkened streets at night is a bit of a shock. "Oh! Um! Yeah, sure." She shifts the bags in her hand and pulls out her phone, unlocking it, before handing it over.

"Forget your phone or just run out of power?" Casual conversation. Just be casual. They hadn't said anything about exchanging gifts, so he doesn't need to know about this. Play it cool, Donna.
