That, Rose wouldn't dare argue with. Mr. Sparkly King was no Time Lord. She may have only seen two of the Doctor's regenerated forms, but both had been a thousand times more human - and better looking - then Jareth could ever be. Even if he wasn't exactly human himself.
On her way to being happy? How? How in God's name could she be happy if it didn't involve traveling with him? Did she want to ask? Oh, hell yeah. Most definitely. But she wouldn't. It had occurred to her during the course of the last few minutes that she didn't want to know about this future. Her world was safe, and so was his. That was what mattered, in the end. That and his hand was in hers the way it had always been before. "Invasions are so yesterday, Doctor," she teased him, nudging his knee with hers. "These days it's all about the ones who get kidnapped by over-dramatic goblins. And up and change genders. Oh, yeah! And vampires. Don't forget the vampires."
Was she actually getting excited? Yeah, probably. But how could she not? It really was sort of like old times. Creatures she'd only dreamed of, a mystery to solve, wrongs to right, and this extraordinary man at her side. Rose gave his hand a squeeze, leaning her head against his shoulder.
