Liam was left devastated when Bernice accused him of being a serial killer, before discovering he was simply a murder mystery enthusiast, and Jonny is unsure if the pair will be able to work through it.
Jonny told Inside Soap magazine: “He loves her, but if your partner thinks you could murder someone, that’s a stumbling block!
“She goes to so much trouble by organising a Wild Wild West event – it’s a touching declaration of her love.”
And Samantha Giles, who plays Bernice, admitted she is also unsure if the couple can make it work, even though Bernice is planning to propose.
She said: “I don’t know if Liam will be her happy ending but I think there is potential there.
“They are well suited, they both have quirks. I think Bernice will want a big extravagant wedding if they do get married – she’ll want to dress up and it’ll be fun. But Bernice doesn’t get a happy ending usually does she?
Meanwhile, Jonny recently said he thinks Liam is becoming a “nerdy” comedy character and joked that bosses have turned his alter ego into a combination of actor Hugh Grant, and Steve Coogan’s comic creation Alan Partridge.
He quipped: “Increasingly, I’m being written as a cross between Hugh Grant and Alan Partridge, but I’m delighted about it as it’s lots of fun.
“It’s all about enhancing aspects of yourself. In real life I’m not as geeky and awkward!”
Emmerdale is on Monday to Friday at 7pm with an extra episode at 8pm on Thursday on ITV.
