Home and Away confirms Levi's new enemy as three characters return

Mackenzie is mortified.

Home and Away's Levi Fowler is called out for being a love rat next week as he meets Mackenzie Booth's extended family for the first time.

Levi's past comes back to haunt him as Dean Thompson, Ziggy Astoni and Karen Thompson all return for guest appearances.

It's Levi's idea to visit North Queensland for a holiday with Mackenzie, wanting to mark the beginning of a new chapter now that his divorce has been finalised.

Levi suggests that he could meet Dean during the trip, which leaves Mackenzie fearful as she knows that it won't be smooth sailing with her outspoken brother.

"Dean left Summer Bay a few months before Levi arrived, so they still haven't met," our Home and Away source reminds us.

"Mac is still in touch with Dean and she knows that he isn't impressed over how her new relationship started with a scandalous affair last year."

Levi and Mackenzie decide to surprise Dean and Ziggy by showing up at their home without any warning.

Dean is delighted to see Mackenzie, but he's far from friendly towards her new man. Rather than offering a warm greeting, he orders Levi to explain himself for pursuing his sister when he was a married man.

Dean's mum Karen also weighs in, wanting all the juicy details of how Levi's betrayed wife ultimately found out.

"Mackenzie is mortified by Dean's behaviour. She knew that he was unhappy but this is worse than she'd expected," our insider adds.

"Ziggy is willing to give Levi a chance, even though she hates affairs after being cheated on herself a few years ago, but Dean refuses to budge and Karen doesn't help matters either."

Mackenzie and Levi end the first day of their holiday feeling like they've made no progress with Dean. Will Levi have to give up and accept that they'll never be friends?
