He'd dubbed her 'jeopardy-friendly' for a reason, and she really did have a tendency to wander off. It wasn't intentional, Rose just had a natural curiosity for things that went on around her. That curiosity hadn't always led to bad things, after all. Her desperation to meet the alternate universe version of her father had led the two of them, plus Mickey, to stopping the invasion of the cybermen. Sure, they'd almost died in the process, but how was that anything new?
A tiny little part of Rose found a hint of vindication in the fact that the Doctor was stuck on this planet, just the same as anyone else. That tiny little part was that piece of her that had been angry with him, knowing what she knew about being able to break through dimensions and yet he hadn't figured it out for her. She'd been trapped on a plain, every day Earth while he continued his voyages around the galaxy.
But it was difficult to be angry when he was holding her, protecting her as he'd always done before that day in Canary Wharf. With a gentle smile, she laced her fingers together and propped her head on his chest, looking up at him with a sparkle in her eyes. If only he'd mean that how she wanted him to. "I think you just miss my French toast," she teased him, though she dropped a playful kiss against his chin. "And my singing in the shower, you know you miss that lovely sound echoing through the TARDIS. Even more when she sang along."
She was really coming back. For whatever time this Jareth person was keeping her for, and longer if she could manage. She'd be home, in the blue police call box that had been such a major part of her life. It didn't get better than that.
