Big revelations, stunning surprises and heartbreaks come into play on this week’s episodes of “Neighbours.” After the shocking return of Dee Bliss (Madeleine West) -- who turned out to be a fraud and is actually a woman named Andrea Somers -- another familiar face makes her way back to Ramsay Street, rocking Jarrod “Toadie” Rebecchi’s (Ryan Moloney) world once more.

Spoilers suggest that the mystery visitor is another woman in his past, Sindi Watts (Marisa Warrington), whom fans haven’t seen for more than a decade. The arrival of Toadie’s “dead” wife was enough to rattle Sonya Rebecchi (Eve Morey) – the appearance of another ex may just be the straw that would break the camel’s back.

The Feb. 6 to 10 episodes will also feature Mark Brennan (Scott McGregor) and Stephanie Scully (Carla Bonner), who struggle to deal with their emotional break-up. “Neighbours” fans wonder whether there’s a chance for the two to work things out, or it’s really time for Mark to cope with being a single dad.

Digital Spy reports that Monday’s episode shows that despite his pain and confusion, Mark still makes an attempt to win Steffy back by asking her to spend the night with him. However, it seems Steph is still mulling over her feelings for Victoria and can’t quite decide yet if she really wants to be with Mark again.

On Tuesday, Sindi makes quite a splash when she arrives in Erinsborough. Toadie finds himself buried in more problems, now that another woman has been thrown in the mix. Meanwhile, Piper Willis’ (Mavournee Hazel) parents decline her request for a loan. However, the feisty youngster refuses to be defeated and makes a move that catches Terese Willis (Rebekah Elmaloglou) and Brad Willis (Kip Gamblin) off-guard.

Wednesday’s run centres on Amy Williams (Zoe Cramond), who hires one of the disadvantaged kids to help her do some repair work at The Flame Tree. Unfortunately, it ends up in a disastrous accident. Amy realises, however, that it may have been done deliberately and Leo Tanaka (Tim Kano) is somehow involved. Elsewhere, Toadie finds out that there’s no money left for Dee from her family’s estate. He wants to help her out financially – a move that may not bode well on Sonya.

The installment on Thursday continues the story on The Flame Tree catastrophe. Amy feels responsible for the incident, which cost Paul Robinson (Stefan Dennis) a big opportunity. Amy confirms that Leo’s behind the “accident” as an act of revenge against her dad, but her feelings for him stops her from doing what’s right. Meanwhile, the Canning-Kennedy fight escalates, making it harder for Xanthe Canning (Lilly Van Der Meer) and Ben Ian Kirk (Felix Mallard) to be together.

“Neighbours” wraps the week with an episode that features Jack Callahan (Andrew Morley), who offers Paige Smith (Olympia Valance) some help as she goes through her pregnancy. She accepts his surprising offer, seeing it as an opportunity for Jack to be involved in their baby’s life. Friday’s episode also shows Mark resorting to alcohol to drown his problems with Steph. Things get out of hand, prompting Tyler Brennan (Travis Burns) to take a drastic move.

“Neighbours” also stars Karl Kennedy (Alan Fletcher), Susan Kennedy (Jackie Woodburne), Elly Conway (Jodi Anasta), Sheila Canning (Colette Mann), Gary Canning (Damien Richardson), Ned (Ben Hall), Aaron Brennan (Matt Wilson), Lauren Turner (Kate Kendall) and David Tanaka (Takaya Honda).
