Donna climbs the hill carrying a plate. "Mum made you a sandwich." She doesn't quote her mother's actual words: Bad enough that daft old man is looking for things that don't exist. If he doesn't eat, he'll get sick, and I'll be stuck nursing him.
"Ta, Sweetheart." Her grandfather doesn't look away from his telescope (a waste of good money, Sylvia says). "I think I saw something. If I adjust the focus-"
"Grandad, come inside. It's getting cold."
"You think I'm mental, too, don't you?"
"Grandad, no. But it's hard to believe-"
"They're out there, Donna! The stars are real."
