The very first arrest (probably of many, let's face it) of Lucy Beale's murder is made tonight following Lauren's statement. She is adamant Jake is the killer and soon the whole square will be thinking it. Seeing as we are not going to find out who the real killer is until next year though (when nobody will even care anymore), we know it mustn't be Jake. Although he has been acting very suspicious whatever is going on with him. Also tonight, guess who arrives to the square? Only Mrs Doyle herself! Pauline Mclynn makes her EastEnders debut tonight as Yvonne, mother of Charlie Cotton. Another very suspicious fella, just WHAT is going on with him and those undertakers?
