Yes, I noted that issue in my original comment, but you edited it out of your reply. I can't explain that definitively. I'm sure we don't have all the information to piece things together.Except she didn't. She told Jack where he could find his old man and he did in fact check up on him.
Like I said, it's a guess. I feel like Beverly had other reasons for keeping them separated. Maybe she thought that the danger had passed. She indicated that when Jack was small, he had sleep issues that were apparently more dangerous that just that. Maybe she thought it was safe after those issues passed?

We'll have to wait and see!
