I've been watching for a while and I've absolutely no idea what has suddenly turned Bobby Beale into a mini Damien, unless it's the fact he's addicted to Minecraft and video games.
The only plausible fact I can see is the years of neglect. The fact that whenever he's in a scene he's quickly asked to leave the room or go upstairs.
I suppose that would get to you after a while. (As published on Digital Spy: http://forums.digitalspy.co.uk/showthread.php?t=2097686&highlight=)
