Lloyd Mullaney's physiotherapist daughter, played by Krissi Bohn, nurses Sophie over the next few months following her road accident caused by Ryan Connor last night (October 24).
The treatment will bring Jenna and Sophie closer to one another, reports the Daily Star.
An insider said: "She's breaking a serious moral code by getting involved with Sophie. Sophie is in a very vulnerable position following the car accident.
"If Jenna's bosses find out they could end her career. If that wasn't enough, Jenna hasn't come out to her parents."
The source added: "So they may have all these feelings for each other but they are going to have to weigh up whether it's worth the chaos."
The pair are worried that their ten-year age gap will be difficult for their parents to accept.
Sophie's dad Kevin (Michael Le Vell) will apparently also develop feelings for Jenna, further complicating the situation.
Brooke Vincent, who plays Sophie, confirmed earlier this week that there will be a new romance.
In a new interview with Digital Spy, Vincent said: "It's more of a love interest than an actual girlfriend and we'll have to see how it goes."
