“We don't actually get up in the morning, for a start.” She hears Oaks' reply when
{...you cannot trust them...}
It's just there, in her mind, another voice. The voice she's always heard. But it isn't singing now, just talking. Picturing the word in her mind, she replies:
[Hello?]
{...hello...}
[Who are you?]
{...you know the answer to that...}
[What does that mean? No, forget that. What do you want?]
{...can I start by offering you an apology...}
