It says here, that John, as we told you, keeps Chesney and Kirk "hostage" along with Charlotte's parents in the basement in their home. He then flees, but it's not entirely clear whether he makes it seem like he's off to kill himself. He disappears and, in reality, is hiding in the small loft in Number 5, sneaking out at night to get food and see baby Hope.
His is discovered and when he pushes past Fiz while trying to run with Hope, she is knocked over and injured. He goes to see her in hospital and then, with the baby in arms, goes to the roof of the hospital (just like Claire) and threatens to jump.
So, here's my take on it. He won't jump with the baby though the article says nobody knows yet if he will take Hope with him over the edge. That's just silly. They won't do that and we all know it. I think he'll hand over the baby and maybe even agree to come down but lose his footing and fall accidentally. Thus, no actual suicide. We all know they rarely go that route though it has happened. John has killed Charlotte and Joy and soap morality dictates he must pay for that. (And before you say it, even Tracy was found guilty and spent a few years in prison. Technicalities do happen.)
