The actress confessed that she cannot see a future for the pair as Cindy appears to have fallen for Rhys Ashworth (Andrew Moss) during their recent fling.
Tony (Nick Pickard) is set to find out about the affair within the next few days, but he goes ahead with the wedding plans regardless - secretly planning to humiliate Cindy by publicly exposing her infidelity at the ceremony.
In the end, a torn Tony opts not to go ahead with his revenge plan and the wedding proceeds without a hitch. However, when Tony spots Cindy preparing to run away with Rhys at the reception, he doesn't have time to react as the sixth formers' out-of-control mini-bus comes ploughing through the venue.
Waring told All About Soap of the scenes: "At the wedding, Rhys has decided to leave Hollyoaks and asks Cindy to go with him. Her head is saying stay with Tony, but her heart belongs to Rhys. She makes the choice to run away with Rhys, and Tony spots them - just as she looks up and sees the bus coming right for them!"
Asked what could happen if Cindy survives, the actress replied: "There'd be a lot of repercussions following her decision to run away with Rhys on her wedding day. She has a load of secrets. I don't know if she and Tony could have a happy marriage - I'm not sure they can recover from her leaving Tony for another man on their wedding day. It's unforgivable and the final nail in the coffin."
Waring also confessed that she regards Darren Osborne (Ashley Taylor Dawson) as the best match for Cindy, rather than Tony or Rhys.
She said: "They're soul mates and so great together. It would be brilliant to revisit that, even if they were just best friends - a 'will they, won't they?' story. I'd love viewers to be rooting for them rather than for them to just have an affair - that's been done too often before. There was something magical between Cindy and Darren."
