Seb will return to Coronation Street next week as Nina starts to remember exactly what happened on the night that she and Seb were attacked.
Monday night’s double bill of Corrie features flashback scenes which take Nina and the viewer back to that fateful night in May when Seb was brutally murdered.
For the first time the audience will find out who was responsible for the cowardly and senseless crime.

Harry Visinoni, who plays Seb, said he came back specially to film the scenes a couple of months after his final day on set.
Harry said it was "special" to return to the soap and be able to film with his colleagues, he said: "It was brilliant to come back and see everyone. We did lots of night shoots so it was very different to usual filming. It felt special and more like doing a self contained drama or a film.
"The atmosphere was different and we worked as a close cohort to be able to show the attack and the build up to it.
"It made it a lot easier, the first time was shot very cleverly and it was left to the public’s imagination, not seeing it didn’t hamper the story telling but for the flashback it was important to show what actually happened.
"It was necessary for us to be able to work closely. It will be interesting to see what is shown in the final edit as the viewer needs to see exactly what happened.
"The viewer thinks they know what happened and who they believe but the audience needs to see exactly what happened to know if justice is done in the courtroom, that is what gives it the drama.
"Thanks to these scenes the audience has the advantage of knowing the complete truth and knowing exactly who needs to be brought to justice."
Harry said he watched his final scenes and while he was unaffected his family were upset.
He said: "I watched Seb’s death with my mum and my girlfriend and they found it really upsetting to watch. It didn’t affect me, I was just remembering filming the scenes but it must have been hard for my mum watching her son in that situation.
"I was more affected by watching the other scenes with Nina, Roy and Abi, they were all so brilliant and I was so proud to have been a part of that story with those fantastic actors.
"The response from the public was incredible. The shock that Seb died was huge and the reaction on social media was huge. Everyone was so lovely and I still get people stopping me now saying how much they were affected by the storyline."
*Coronation Street continues at 7:30pm on ITV tonight
