We really don't know what had been flagged at what time, so it's not possible to cite it as fact until we get a timeline. They were still at the hospital at around 11.30pm ish which was five hours later, and so it's not as if we can say for sure that things were just assumed to be non-suspicious. He hadn't been discharged yet, because they were all still there for later interviews. It's possible conversations were still being had, with the parents, and possibly also between doctors behind closed doors, when the emergency with Leon came through.
