A/N: A bit of a shorter one (sorry) but a tad more Amy/Eleven in this one. And a puppy. Because you can't go wrong with a puppy.
He finds a toothbrush with a blob of blue nail varnish discarded somewhere as he hunts for his dog collar (not his dog collar; a collar for a dog. A collar for a dog Amy will not, under any circumstances, leave on its own.) The toothbrush stops him dead and he picks it up, placing it on the shelf he labels 'MJ.' Beside it sits a little red cap with the same initials embroidered onto it and next to the that sits a stethoscope which he pats affectionately.
"Doctor?" Amy comes looking – puppy in her arms – and sounds a little unsure as she finds him. "You're petting a stethoscope?"
"Yes, Pond. That is what I'm doing." Amy notices the initials and almost drops the dog, who lets out a tiny whine.
"Don't tell me they're Michael Jackson's!" This is the most excited he's heard Amy and he's a little bit miffed. He's shown her planets made of metal and the birth of the first waterborne humans but she gets more excited over the King of Pop.
"Why would they be his?"
"MJ! That's what it stands for, right?"
"Wrong," he looks at Amy as if she's dribbled down herself. "They're Martha's. Martha Jones. She saved the entire planet, you know."
"And you keep a shrine of her?"
"It's a shelf, it's not a.. shrine." The Doctor leaves the shelf and re-starts his search for the collar. "Ah! Got it. Although," he holds it up next to the little puppy in Amy's arms, talking directly into his large brown eyes. "Might have to grow into it, little one."
He takes the puppy from Amy's arms and walks out, leaving Amy staring at the shelf. Is this what he does? Let people go and replaces them with shelves? Not for her; if she ever leaves (which she swears she won't) she wants more than a shelf. Amy Pond will have an entire library of shelves, and she intends to tell the Doctor so.
Right after they take Rolo for a walk (and no, he doesn't know that's what they're calling the dog yet.)
