Not only does Hayley manage to clash with Michaela within minutes of arriving, she also has Zak's blood boiling when he catches her in bed with Archie!
Ladies man Archie isn't exactly the type of guy you'd like your sister to date, so you can imagine Zak's horror at the thought of his sister sleeping with him.
An angry Zak even punches Archie, infuriating Hayley who is adamant she'll live her life the way she pleases.
Can Hayley and Zak mend their relationship, or has Zak taken it a step to far? Tune in next week to see Hayley arrive in the village.
