Scott and Annalise (Tamaryn Payne) have harboured feelings for each other for some time, but have so far shown no signs of becoming a proper couple.
However, Demba told Digital Spy that next week's Hollyoaks episodes - which explore a turbulent time for Scott at home in London - could prove to be a turning point for the story.
Demba commented: "What happens to Scott when he's back in London does give him a different attitude towards life. It feels like he needs to man up and start facing his problems head-on.
"He really needs to seize the day, so when he does come back to Chester, he's meaning business. He's going to try and sort this out once and for all."
Scott is good friends with Annalise's ex-boyfriend Rob Edwards (David Atkins), which could complicate the situation.
Demba added: "I think Rob is always a factor that looms in Scott's head, and it must be the same for Annalise. But this has gone on for quite a while now. There's been lots of looks between Scott and Annalise, and they've flirted quite outrageously at certain points! I think it's going to have to come to a head.
"Scott knows that Rob's not going to be too happy about it, but sometimes you have to ruffle a few feathers! Scott sees that something is out there for him, and if he's got to upset Rob a little bit, then that's just how it's got to be."
Hollyoaks airs weeknights at 6.30pm on Channel 4 with a first look screening at 7pm on E4.
