Mickey wanders around the TARDIS, marvelling at how big it is, although he's sure he still hasn't discovered all of it, and still gets lost constantly.
The Doctor had sent them whirling into space and was now admiring the ingenuity and imagination that must have led to the invention of the slinky.
"Rose this is brilliant! Why didn't you ever tell me about these before?" He is running around after it letting it slide down every possible surface he can find.
Rose is sitting in the seat near the console. She smiles warily at the Doctor. He had found the slinky in the school. A kid must have dropped it when it was running away.
The Doctor had brought it into the TARDIS and set it down on the console. He had looked at it from several angles and even prodded it with a pen at some point. He had lifted the top up slightly and let it fall back.
Rose had been showing Mickey his room, but when she came back, the Doctor was not much further in his discovery of the slinky.
He eyed it suspiciously from a short distance, his arms folded.
Rose had gotten to know the Doctor quite well these last few weeks and knew he would soon start feigning boredom with the object to hide the fact he didn't know what it was.
She walked up to the slinky and lifted the top.
His eyes followed her movements eagerly, reminding her of a dog waiting for you to throw his toy.
She moved the top over the edge of the console and let it go.
She didn't watch the slinky hit the ground, instead she focussed on the Doctor's reaction.
She got the reaction she was hoping for. The one that made her heart spill over for this curious and strange yet irresistible man.
His eyes grew wide and started a smile that quickly spread over his entire face. He looked up at her for a second before quickly focussing on the slinky again, which was making its way down several steps away from the console.
The Doctor followed it and got to his knees to examine it close up. If he had had a tail, Rose was sure it would be wagging enthusiastically.
