Neighbours’ Karl Kennedy to issue Darcy warning – is he already crossing the line?

Neighbours spoilers follow.
Neighbours‘ Karl Kennedy will issue a warning to Darcy Tyler in upcoming scenes as he starts to push the boundaries.
Darcy recently returned to Erinsborough after 20 years away, with his aunt Susan agreeing to give him another chance despite his history of misdeeds.
Next week, Terese is intrigued when Darcy offers to keep a close eye on Chelsea, who Terese has been feeling insecure over since she returned to town with Paul Robinson’s newborn son Thomas.
In return, Darcy wants to start working at Eirini Rising on a part-time basis, where he’d be job-sharing with Karl.
When Terese reluctantly agrees, Darcy holds up his end of the bargain by getting closer to Chelsea, and the pair even start dating.
Paul is furious when he hears about their relationship, while Terese is privately unsure what it means for her deal with Darcy.
When Paul eventually calms down, he’s able to realise that Chelsea could block his access to their son if he gets on the wrong side of her, so he brings himself to apologise.
Meanwhile, Darcy assures Terese that he’ll still honour their agreement, as he doesn’t want to see Chelsea and Paul together either.
Later on, Karl is put out when Darcy moves his things into their newly shared office and takes over his consult with Gino.
His concerns grows when Gino later expresses interest in the investor information session for Darcy’s health centre.
Karl warns Darcy that asking residents for money is unacceptable. Is Darcy starting to push the boundaries already?
