Coronation Street actor Andrew Still teased there could be a devastating result during his character's trial, as Justin faces prison for the horrific acid attack he committed earlier this year.
Justin attempted to throw acid in the face of Daisy Midgeley after stalking her for months, with him turning nasty when she rejected him.
Ryan Connor jumped into the path of the acid to protect Daisy, and he ended up suffering from severe burns to his face and body.
In the fallout, Justin was arrested and next week he will appear in court - with Daisy and Ryan tasked with giving evidence.
Ryan initially refuses to face Justin and go to court, and soon Daisy finds herself panicking as it isn't long before Justin begins manipulating the true events in front of the jury.
Speaking ahead of the scenes airing, Justin actor Andrew revealed there's a chance he could get away with his crime as the character tries to trick the jury.
He said: "It's a bold play by Justin! Viewers are really not going to know until the end which side the coin is going to fall on."
Andrew also confessed he wanted his character to face justice for what he did, saying: "Yes, definitely. When I have been a viewer of a show and watched a character do terrible things, I can’t help but hope that it’s going to come back to bite them and I think that Justin certainly deserves justice to be served because what he has done has been horrendous.
"I definitely think he should get his comeuppance."
On what happens in court, he went on: "Justin has a well rehearsed speech as he knows this trial is important so he sees this as his golden opportunity to convince the jury to let him go.
"He is going to put on the full charm offensive and he will use all of his manipulation tactics to win the jury round. He’s not confident that this is going to all pan out for him but he knows that this is make or break and he has to put on the performance of his life to get away with this.
"It’s a very stakes, high pressure situation for him. We are going to see the most manipulative Justin yet. It’s a new Justin that we are going to see.
"There is a lot going on in his head with the trial underway as he feels backed into a corner so he is willing to go to whatever lengths he has to, to gain the upper hand.
"He has manipulated his sister and he is lying to anyone and everyone around him. There is a very definite fear of going to prison for a very long time so he is desperate.
"We will see a slither of the pathetic Justin but this is his big chance to be seen and to be heard, particularly by Daisy, so he is happy to grab that opportunity with both hands.
"As the trial progresses we are going to see Justin wrestling to stay calm and collected as this inner tension is bubbling under the surface."
Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITV X.
