[Thomas steps forward hesitantly, eyeing the Pidgey. When he nears the egg, he stands over it and sighs. He turns to N.] Look, tell her -- wait, I will. [Frowning slightly, he faces Pidgey.] I don't know anything about hatching an egg; we never kept chickens on the estate and -- Anyway, you're a bird, this is an egg.

[Feeling very foolish, he raises his palms and struggles to continue. The Pidgey just stares back, confused.] If you promise not to peck at my head or anything you could keep caring for it? I guess I'd have to catch you to make this legitimate, can't just leave the egg out here, after all... [Thomas glances towards N and shrugs.] I don't know, would that make sense?

[The Pidgey seems to catch the gist of what Thomas is proposing and looks eagerly from Thomas to N. Your friend gives egg to me? ]
