- What is it, darling? Come on now, stop crying. Did you get separated from the others?
- Let's go downstairs, where it's nice and warm.
- No. Stay with me. It's better now you've come.
- Isn't it silly of me? I don't remember noticing you downstairs.
- Are you one of the Headingly children?
- My name is Francis, Francis Kent. It is my bedroom, mine and Constance's.
- She's my half-sister. She's grown up, like you.
- I didn't notice her either. All the other girls seem much younger than me.
- I wish you were my sister. You're so kind and nice.
- Why? Is she unkind to you, darling?
- She hates me. She said she'd like to kill me.
- Oh, don't. You poor little thing.
- But it'll be quite different now, now that I've met you. I'll be able to sleep.
- Poor Francis. Come along, I'll help you.
