This week, Owen slaps Anna's foster daughter Faye, leading to the couple's break-up.
But Puleston-Davies believes Debbie Rush's character will reunite with Owen, telling Soaplife: "I hope [they get back together].
"I think when she calms down and when she hears enough of his defence he'll be able to persuade her to realise that it was a mistake, that he's accepted and acknowledged it was wrong and that he crossed the line."
The 53-year-old added: "He believes that their love is stronger than this mistake and he believes it won't ever happen again."
Chatting to Digital Spy, Rush revealed that Anna will find it "very difficult" to trust Owen following the slap.
