Neighbours star Ashleigh Brewer has revealed that her character Kate Ramsay will be "torn" and "confused" when ex-boyfriend Mark Brennan makes his shock return to Erinsborough.
Kate is dating new neighbour Mason Turner (Taylor Glockner) when Brennan arrives back later this year.
Brennan (Scott McGregor) was thought to have died in witness protection in 2011, so his unexpected reappearance will turn Kate's whole world upside down.
Brewer told Digital Spy of the upcoming storyline: "I think it was great to bring Mark back. There are so many unanswered questions - not only for Kate but also for the viewers. We all became good friends with Scott when he was here last, so it was great to have him back, although it was too short.
"Kate is in absolute shock when Mark returns - it really rocks her. She has worked very hard to move on and now things are just starting to work with Mason, so it's a very confusing time. She's torn.
"The feelings are definitely still there between Kate and Mark but lots has changed, so who knows what will happen?"
Scott McGregor has already filmed his return scenes as Mark and will be back on screen for a month.
Asked whether the actor is likely to return permanently in the future, Brewer replied: "I can't really answer that, but he certainly has a lot on the go at the moment. Now we have established he is alive, there is no stopping him making a return visit, and that happens a lot on Neighbours."
On the current Kate and Mason pairing, she continued: "Kate is certainly attracted to Mason's cavalier attitude which is quite different from her, so he is intriguing. I think she is enjoying the attention and let's face it, she hasn't had a lot of luck on the love front lately! I think they have potential as a couple."
Brewer also teased another big storyline on the horizon for Kate, hinting that things will be getting even more complicated for her.
She said: "This [story] also involves her love life and the repercussions of a 'moment' she has with someone and how this impacts on other people."
Neighbours airs weekdays at 1.45pm and 5.30pm on Channel 5 in the UK, and weekdays at 6.30pm on Eleven in Australia
