[spoiler]Sunday's quote:
Ep #1146 (1840) - Daniel - 'It will ruin us. It will ruin us all. I MUST stop it. I will stop it!'
From "#1146/1147: Robservations 10/29/03: The Real Daphne, Revealed"
Quentin, Daphne and Gerard enter the bedroom. Quentin rushes to his father's side. You, you, you're not who you say, you're not the man you were, gasps Daniel. (How ironic, considering GERARD is the one who has changed--to another person!) Edith tries to force Quentin to leave. Get away, says Quentin. Edith tells Daphne and Gabriel, Daniel is too ill for company. Gerard leads Daphne out of the room. Why what? Quentin asks Daniel, who mutters, "It will ruin us all--I must stop it, I will stop it!" You want Daniel to die, accuses Edith. Get out of here, Daniel orders her. But Father Collins, she protests. Leave this room! he cries. Get out! shouts Quentin. Edith takes the hint and goes. I saw your stairway, says Daniel--I saw the past--you killed Lorna! No I didn't, says Quentin. Daniel passes out.
