Kim and Ray (Chucky Venn) have experienced various ups and downs since becoming a couple earlier this year, and Empson told Digital Spy that there could be more challenges to come.
Speaking at the 2012 Inside Soap Awards, Empson commented: "It's never happy go lucky - I think Kim is still breaking him in! But will he resist, will he play along? Who's to say? Keep watching."
Discussing the possibility of Ray showing new sides to his personality, she continued: "Maybe he's got a dark side, and how do you think Kim would handle it? Will she cope, won't she cope?"
EastEnders took home the 'Best Soap' prize at last night's (September 24) event, and Empson suggested that Janine Butcher's storylines stand out as some of the show's recent highlights.
She said: "It's lovely to see Janine tested… becoming a mother and being a career woman. That's interesting - I think it will affect a lot of people, especially a lot of young ladies."
Empson added that she was "very proud" to secure the 'Funniest Female' gong on the night, having also triumphed in the comedy category last year.
On the possibility of another victory in 2013, she said: "Let's see. I mean, these are balancing out on my mantelpiece. A third one would be lovely, but I don't know - I'm enjoying this as it is!"
The Inside Soap Awards, sponsored by online fashion retailer boohoo.com, were held at One Marylebone in London.
