Peggy vs Lauren

Synopsis
The scene is set when Lauren arrives in Walford in search of revenge on Stacey Slater, who has apparently stolen her boyfriend. She looks for her in the launderette, where she finds Little Mo Mitchell, who tells her that Stacey is not there. She then makes an appearance in the Queen Vic, and Peggy Mitchell finds herself getting increasingly frustrated with Lauren, who asks, "Are you a Cockney? Are you a Cockney sparrow?" (pronounced "cockerney"). Peggy then orders Lauren out of her pub with immediate effect.
