Ruth pulled a chair up to the patient's bed.
"You said you wanted to speak to me," she started.
"Yeah, alright, listen. Rachel isn't actually my grandmother. She was a human who I knew for a very long time. I'm not John Smith. Fingal Smith is some random person living in Ilfracombe. My real name is the Doctor. And there is something in this hospital that you don't know about, that will kill all of us."
"Why are you telling me this?"
"You believe me?" He looked at her quizzically. She sighed.
"Normally, I would say you need a brain scan, but...I believe you." The Doctor smiled warmly.
"We need to tell one more person. We can take it, but we need to be a team of three. After all, a team of three is better than a team of two. Who do you have in mind?" Ruth could only think of one person: Toby.
