The Doctor was in the TARDIS with you his child adopted child. (He calls you kiddo)

Before The Doctor had regenerated, he had adopted you... Hes very protective over you and he’d kill and die to keep you safe from all the danger in this cruel world.

One day while The Doctor was fixing TARDIS controls, you were sat beside the Doctor watching TV.

"Hey kiddo could you please pass me my screws I got everything else except the screws!"

he chuckles to himself
