Just saw the spoiler. We noticed that when he took the kids bike back, they weren't in the back of the car but he unloaded them.I liked it, but I had one glaring issue with the last episode
There was no real hint at the brother until 20 minutes before the end he decides to go really weird at the policewoman and trigger suspicion, then suddenly it all very quickly unravels from there. If he was clever enough to literally get away with murder for seven years suddenly he's too thick not to give the game away in a couple of seconds?
