It’s implied by the prosecution but it doesn’t actually say what he was thinking, it says he was starting to notice the coincidence it was always Lucy and had concerns.He’s the same doctor who in the baby k incident he doesn’t think she’s incompetent wouldn’t you agree
What are you not buying though, he’s admitting he wished he did more. Do you think he’s lying about having concerns or are you just in disbelief he didn’t take it further? If he is genuine I’m sure he is kicking himself every day, it would be very hard to live with, knowing you could and should have done more.
