“Right then,” The Doctor said from the entrance of his TARDIS, “I'll be off, unless," The Doctor hesitated, "I don't know, you could come with me. This box isn't just a London hopper, you know. It goes anywhere in the universe free of charge.”
“Don't.” Mickey said to Rose, grabbing her hand to try and keep her from leaving, “He's an alien. He's a thing.”
“He's not invited.” The Doctor nudged his chin at Mickey, “What do you think? You could stay here, fill your life with work and food and sleep," The Doctor stared, silently pleading to Rose, "Or you could go anywhere.”
Rose bit her lip, contemplating, “Is it always this dangerous?”
“Yeah.” The Doctor said bluntly, but with a smile. He had so much expectation, so much hope in his eyes that his new friend would come with him into the vast and beautiful universe. He wouldn’t have to be alone again, not for a while at least.
Rose sighed, closing her eyes and forced herself to shake her head, “Yeah, I can't. I've er, I've got to go and find my mum, and someone's got to look after this stupid lump, so.” Rose twisted her hands behind her back,
A moment passed before the Doctor responded with a quick nod, “Okay. See you around.”
The TARDIS dematerialized.
“Come on, let's go.” Rose began to pull Mickey away, “Come on. Come on.” Rose let go of Mickey and watched him walk ahead of her, turning the corner out of the alley and back onto the main streets of London. In a moment to hope, she turned back to face where the TARDIS once sat and waited.
A second passed. Two.
Rose sighed in defeat. Why did she think that he would come back for her? He was an alien, a Time Lord, he probably didn’t care about a measly human like her.
“Rose?” Mickey called from outside the alley, “C’mon, your mum’s looking for you.”
“Alright, I’m coming,” Rose called back, taking one last second to think about the missed opportunity, the long-gone future she could’ve had before turning on her heel and stalking out of the alley. Back to her mundane, routinely life.
