I have a theory, The boys meet Max and then find a gate to the upside down and do not find eleven. So then they try to find their way out and make it out, then then in about an hour Eleven makes it back from the upside down and then that's when the episode finishes. Episode two, Will starts to see things again and gets trapped in his mind for a while and sees the thessalhydra then stops seeing the upside down and then Will goes to see a doctor. That's what I think of the first 2 episodes.
