A shocking plot spoiler in News of the World today says that David Platt's anger and jealousy overflows and he is going to attack Tina.They're calling it a "rape plot" but they don't actually say he rapes Tina though it's implied. On one hand, you can see how this might happen, with David so filled with rage but on the other hand, I can't see how the character would have any future in the show if it did happen.
It's one thing to have a non-permanent character be involved, like the rape of Toyah Battersby by an acquaintance back in 2001. But for a long term character like David to do it would utterly ruin the character and he's very popular with viewers. He's done a lot of bad stuff but this would be the worst if he goes through with it. Perhaps it's a red herring, perhaps it will be a near thing, but if they do this, I think a lot of people might just turn off the show. This might fly on EastEnders, but Coronation Street fans won't have it.
