While the gang are threatening the pair Ben says to them ' So long as I suddenly go deaf, blind and stupid so far as you lot are concerned?'
If you only just started to watch the show you wouldn't think there was anything wrong with that line. However long time watchers of the show pointed out that Ben was actually deaf. He suffered from meningitis as a child and ended up going deaf. However the show has also said in the past that Ben is half deaf, and now it sounds as if he's not deaf at all!
Some people have just suggested that Ben was being sarcastic, or that the gang of thugs just didn't know Ben was deaf... Though we're not convinced.
Others were also confused by Ben Mitchell's glasses. Why don't they ever break?
