HARRY
You told me you don’t think I’m scared of anything, and that – I mean, I’m scared of everything. I mean, I’m afraid of the dark, did you know that?

ALBUS
Harry Potter is afraid of the dark?

HARRY
I don’t like small spaces and – I’ve never told anyone this but I don’t much like – (he hesitates before saying this) pigeons.

ALBUS
You don’t like pigeons?

HARRY (he scrunches up his face)
Nasty, pecky, dirty things. They give me the creeps.

ALBUS
But pigeons are harmless!
