Treadwell-Collins said, "when told me her decision back in the summer [2015, we both had a little cry before getting excited about how Peggy Mitchell, the matriarch to end all matriarchs could bid her final farewell to Albert Square. In Peggy Mitchell, Barbara has created one of the greatest ever characters on British television, someone who has become as synonymous with "EastEnders" as The Queen Vic itself. So this is the end of an "EastEnders" era. But it is also an opportunity to send Peggy Mitchell out in style in what will be one of the most heartbreaking, uplifting and epic exits an "EastEnders" character has ever had. We can't wait to have Barbara back at "EastEnders", even if it is for the final time. The most professional of professionals on set and off, and a true friend, we have all been working harder than ever to make Barbara and Peggy Mitchell proud." Windsor resumed filming on 21 March 2016.
