EastEnders fans think they have spotted the Christmas "murder weapon" after the Beale and Knight families went to war on Thursday night. While the weapon in question certainly won't be the one that is used during the festive episode, it is almost identical to the one that can be seen in the flash forward episode, which aired back in February.The item that eagle-eyed viewers spotted is a champagne bottle, which George Knight handed over to Ian and Cindy Beale on Thursday, 28 September.
