TV: Eastenders

I have just seen one of the best episodes of Eastenders ever! Not just because of the high drama... but because of the way Peggy spoke her lines at the end of the show, "Let it burn... Let it burn..." It was absolutely hilarious. Where did that voice come from - under her wig????? Has Peggy been body-snatched by an alien???? Surely this is the final twist that sees Peggy leave the show, not in a cab, but in a space ship - Gawd Bless e'r.
