The Doctor and Amelia in “The Eleventh Hour”

So what about your mum and dad, then? Are they upstairs? I thought we'd have woken them by now.

I don't have a mum and dad, just an aunt.

I don't even have an aunt.

You're lucky.

I know. [An awkward pause] So your aunt, where's she?

She's out.

Has she left you all alone?!

I'm not scared!

Of course you're not! You're not scared of anything! Box falls out of the sky, man falls out of the box, man eats fish custard, and look at you! Just sitting there! So you know what I think?

[shrugging] What?

Must be one hell of a scary crack in your wall.
