Were you watching last night's show?

If so, you'll know that Ben Mitchell was kidnapped by the same gang who killed his boyfriend Paul Coker. Ben was beaten up by the group and scenes showed him sitting on the ground holding his arm. However, as eagle-eyed viewers were quick to point out that although Ben had been attacked, his glasses were intact and weren't affected by the scrap. A little hard to believe, to be fair.

#HarryPotter could do with a pair of Ben Mitchell's glasses. They seem to be indestructible despite all the fighting. #Eastenders

From one specky person to another, HOW ON EARTH have Ben's glasses not broken yet?! ? #EastEnders

That's not all either as other people picked up on a completely different issue. As fans of the show may be aware, Ben had meningitis as a baby and this left him deaf in one ear. As a result, he often wears a hearing aid which you might have noticed before. However, that appears to have been forgotten about now as comments on last night's episode showed. The leader of the gang said to Ben:

"It doesn't have to be like this. You and your mate could just walk away..."

Ben's reply was:

"So long as I suddenly go deaf, blind and stupid so far as you lot are concerned?"

People immediately pointed out that going on the previous storyline, Ben is actually already partially deaf and taking that into account, the line doesn't make any sense. Eastenders fans are usually active on Twitter, particularly when a mistake is spotted, and last night was no different. Here's what people had to say:

Remember when Ben Mitchell used to be deaf and loved show tunes and dancing? #EastEnders pic.twitter.com/BMAXBlIH5F

@OldRoberts953 When Ben Mitchell said 'you suddenly want me to go deaf blind and stupid' my girlfriend neatly pointed out he is already!

The EE bosses are probably a little red-faced right about now. Oops.
