I have already watched Castle Season 4 Episode 6, “Demons” about two nights ago. This episode is super exciting, and kids shouldn’t watch it at night. It is about a haunted house, and this time, the murderer is actually one of their own, a detective. Like a basic horror movie, lights flicker, then the murder happens. This episode is definitely an episode to watch, because it’s full of excitement. So, if you haven’t watched it yet, catch it on www.sidereel.com right now, because Castle Season 4 Episode 7, “Cops and Robbers” soon!
