For a moment, Amy lets it feel like a normal day in the TARDIS. The Doctor here, looking excited for adventure, the TARDIS acting her quirky self, the need to rearrange a bit because of some big adventure. She has to allow herself these moments, she's decided, because there's no telling when the Doctor is going to up and leave her behind, like he has the others.

Enjoy it while you can, Pond.

And she does. She tosses the bags aside (they will hopefully still be here later) and bounces up next to him. "Let's try down there," she points, opposite of his direction. "Unless you've got a coin to flip."
