Tosh waved aside Jack's offer of a hand up as she tucked her laptop back into its bag, hitching it over her shoulder. "Of course." She looked over at Jack. "Maybe we should split up, Jack. I'm sure I'll be safe with the Doctor, and you're looking lost. With all the techno-babble, I mean." She gave him an apologetic smile.
"I'll be just fine, Miss Sato." Jack returned her smile, holding out his arm for her. "Only way to get unlost is learn what you're talking about."
Tosh bit her lower lip a moment. "You don't have to protect me, Jack."
"I promised I'd get you home safe, Miss Sato."
"Of course." Tosh looked over at the Doctor. "Well, then. We should get started, as the Doctor suggested." She still didn't take Jack's arm, walking down the street back the way they'd come.
