EUREKA!!!
I'm patiently waiting for a scene where Mike and Robin discover some new information, so they start to discuss it very fast; nobody is understanding what they are talking about. Suddenly, both of them have a realization; they stay quiet for some seconds and say in union some shit like "Eureka!" Meanwhile, everybody is looking at them, thinking, "What are these bitches on?".
I think maybe in s5 they will end up in an upside down mirror of this particular night. Its such a cool theory and just to add to it a little (sorry for the bad quality)
Just a little bit before the lights flicker, Mr. Wheeler is having trouble with the television signal.
Maybe the kids are effecting it from the other side
