There was NOTHING terrifying about the scene of him giving the toy back to the girl. Stop being so dramatic. It was only upsetting in retrospect, after having found out what he did at the end of the episode. You make it sound like it's a crime to be friendly with children. It's NOT.

What does calling someone a pedo have to do with being "overly PC"? It seems like you just like to use buzz words.

Wow, because he was friendly with a kid, it made him a pedophile in your eyes. YOU'RE what's wrong with todays' overly PC and sensitive/easily offended society.

What clues? That was like the first minute. I mean, if someone figured out he was a pedo based on the fact he was friendly to a kid I'd say they're either brilliant or well

Exactly, I just thought that he was a good guy when he was nice to the little girl.

Those viewers probably assume EVERY character has something going on with them, so they are wrong a lot too. My main point was that unless you were being paranoid the child scene wouldn't have meant anything. It was put there for the "oh my god" after the reveal. Makes you see that scene completely different.

Context, though.
Black Mirror
often features characters who are not what they seem on the surface. And we already had a couple of clues by that time that there was something wrong with him.
I didn't catch on that quickly, myself, but considering what we're watching, I'm not surprised that some viewers did. I don't think it says anything about their characters, only that they're observant and deductive.
"Don't call me paranoid, it makes me paranoid!"

yeah it shouldnt mean anything other than he is friendly or like being with kids.

So because he was nice to a kid you suspected he was a pedophile..? This kind of backwards thinking it what is wrong with people! I partially blame TV for it, but who knows.

So far this episode was the most predictable for me. As soon as he look at that girl I knew he was a pedo, and so it wasn't hard for me to figure out what he was being blackmailed for

Yeah I know. I even felt sorry for Kenny, even though he was a paedophile. He was an idiot, but he also had his life ruined because he acted on his wrong desires.

It really was a good episode. Like I said the only I've seen so far. Jerome Flynn was stellar as ever. Can't help but to feel sad for him.

It's my favourite episode in all of Black Mirror, one of the best pieces of TV I've ever seen. The questions and debates the episode can lead to are endless, as can be seen on this message board.
