Ken finds himself suspended from work and tries to engineer a way back in before Lorna finds out. Lorna tells a little white lie and employs an underhand tactic to get Sid in to an exclusive local nursery. Meanwhile, it's full steam ahead for Dale and Steve's new bar - unfortunately for Rachel. But with the meeting to confirm an alcohol license on the horizon, Rachel sees an opportunity to stop it from happening.
