In episode 2 of the Runaways, aptly titled Rewind, we spend most of the episode within the same time frame covered by episode 1, Reunion. This time around, we spend more time with the parents, who are full of secrets. Every family is keeping more secrets from their kids, and each other, than just the true nature of the PRIDE.
The episode opens on the moment when Molly takes her photo of the Pride ritual. The kids and parents all try not to panic. Tina suggests that the flash may have been light from the staff bouncing off the sound barrier she created.
The kids run upstairs and try to escape, but the secret passageway door has automatically closed and locked. Molly uses her new super strength to force it open. None of the other kids realize what she did.
