Once the TARDIS doors were shut tight Rose went straight to the wardrobe room to return her Victorian dress to its ranks while the set the controls to take them into the Vortex. When she didn't return immediately he began to fudge around underneath the control console, seeing to a repair he had been putting off for far too long.
It was over an hour later when Rose finally returned, and because she didn't see him at first she nearly called out his name until she saw a pair of legs sticking out from under the console. She tried to be patient to wait for him to come out on his own but she knew it'd be awhile considering how engrossed he seem to be in whatever he was doing.
She finally walked over to the legs and carefully sat down besides them softly saying, "Doctor?"
"Just give me a second to finish this," he replied in a preoccupied voice.
Rose was preoccupied herself but something she'd seen in the wardrobe just now. "Doctor, in my dreams you wear this face that isn't yours. It's a daft but friendly face with big teeth and you've got a head full of brown curls. Your clothes are different too, very different and you wear this impossibly long scarf that looks like it should trip you up because never does."
"How do you know it's me in the dream then?" The Doctor had emerged from underneath the console and his blue eyes were now watching her. "Does someone call the bloke you're describing 'Doctor'?"
Rose shrugs, "No, he's never called 'Doctor' in my dreams yet something tell me that it is you in my dreams and when I was in the wardrobe just now I saw that same scarf I see you wearing in my dreams hanging off a rack somewhere."
The Doctor laid his sonic screwdriver aside and got to his feet, holding out his hand to her, "All right show me this scarf you're talking about."
They returned to the wardrobe together, and walked several times around the enormous room but Rose never saw the scarf again.
"I know I saw that scarf, Doctor. It was here," she insisted.
"Or maybe you thought you just saw it?" he suggested. "After all a person can't change their face now they they?"
"No, they can't. It's daft to think that they can. I'm sorry I even suggested it."
"'S fine, Rose." He took her hand an began to pull her back towards the console room smiling. "How about I take you home to see your mum? At the very least we need to be sure Rickey made it home safely, eh?"
Even as he spoke the words he thanked the TARDIS for hiding the incriminating woolen object from his former incarnation. Regeneration was a lot to take in and he didn't feel ready or up to the task of explaining it to Rose just yet because he was afraid it would frighten her.
Rose smiled back at him, "Yeah I am missing Mum just a little. And his name is Mickey, not Rickey you silly git!"
