"Kate went to find Mitchell and call an ambulance," Jack explained. He felt slightly less guilty about Becka's death now that Rose and Tony had both had the same reaction, but he knew he'd never be entirely convinced there was no blood on his hands. "I'm a detective, Rose. Talking to people is part of what I do. I thought she might say something useful, or people might need her to still be there. And I was worried she'd go for Kate or George if I left her alone."

He looked bitter. "Of course she ran when the ambulance came."
