Mark is happily seduced by Roxy, who plays down her surprising outburst of romance, so Harlow can escape from hiding, he gets frisky enough to allow her literally dirty poses in his frantically cleaned home. Even in bed at their posh hotel, the 'happy couple' can't avoid worrying about the ominous exes omen, but passes on to holiday fun, mostly beach- and pool-located, until he spots his third, Brazil ex Christina at the bar, which spooks him even worse, claiming he can't go on with the wedding. Shilea spoils Gary's next date by pointing Rebecca is a Paul-ex.

Leo reports he can repay the guy couple having definitely closed down the bar, despite Roxy's whining, but worries about his future. Kyle eagerly tells Gary that Gail still wants to date him, but Sheila pleads Rebecca's case, until he runs away from the choice between Paul-exes. Having shredded her wedding dress, Terese calls Ned, who susses and promises out come, while she puts Paul's luggage out, unwilling to hear his story. However his ex Christina's twin sister Caroline Alessi gets Terese to hear what happened and invites both Paul and her sister about the exes conspiracy.

Stunned by the twin sisters' explanation how Paul's daughter Elle masterminded to exes haunting, Paul can convince Terese to accept his second proposal and go ahead without pomp, using an Elvis impersonator. David is angry at Leo, whom Aaron tries to suss, for his part in the exes scam, actually for the money to repay the gay couple's loan. Ned never made it before Terese reported the wedding was off and waiting for a flight back kindly shouts altar-dumped bride Scarlet Brady, who sneakily manipulates his smartphone to make him miss another flight. Rebecca dumps Gary for 'sneakily' dating Gail, but the latter doesn't mind when informed. David having refuses to hear Leo's apology while celebrating Paul's marriage, Leo leaves a dear John note, seeking to find his own way away from the dysfunctional family.
