I have no idea if she has it in her to write a book about Darrow, especially one that requires interviews with limited interested interviewees. But she's always going to write. As for fiction, probably not? She was raised to write about reality and Darrow's specific reality is far more interesting than anything she could make up.

She'll settle for a healthy son.

It's hard to say. I'm still figuring out how to play someone that's going to lose his memories of the most traumatic event of his life. Having Eddie and Bev would make the transition much easier for sure, though, and he'd be happy to be away from Derry (while he still remembers it) but sad to leave the last place he was with Georgie.
