Robert, John and one of their workers race to buy a generator after the power goes out at their lab and precious samples might be ruined (but this is played fairly lightly).
John steals Robert's security clearance badge with the intent of taking some of the experimental product for his kids without permission. When a guard catches him, the man aims his handgun at John, with Robert then arriving and lying that he sent John to retrieve it for him.
Dr. Robert Stonehill is very intense and yells a lot, very loudly. It might scare younger kids.
John gets a call from Aileen that Megan is in the hospital, and when he gets there, she's been moved to ICU. They get bad news about her prognosis, and when they're later sitting with her, she flat lines, sending them into a panic and the staff into resuscitation mode. We later see the parents and think that she has died, but they get news that she has pulled through.
