Coronation Street fans were left unable to watch during scenes that aired on Monday.
Paul was recently hit by Carla Connor while driving his motorbike, after Carla was drugged by Stephen Reid and therefore shouldn't have been driving. Paul has since gone back to work to help his sister out with a huge bill, though his partner Billy thinks he has returned too soon.
This week's first instalment on Corrie saw Paul and Billy in Roy's Rolls. Paul had a Full English with "extra sausage, extra bacon and extra toast".

He said he needed to keep his strength up for the big day ahead. Scenes that aired later showed Paul using a saw. He became distracted and, had boss Ed Bailey not walked in, he would have probably chopped his thumb off.
Viewers squirmed as his left hand got closer and closer to the moving saw. Taking to Twitter, Jess said: "Urgh I can't watch", while Gav said: "Paulie nearly lost a pinky".
Simon said: "Ffs Paul, it's not safe for you to be working! He would so easily have lost a hand or some fingers just now." Stacey said: "Just spent most of that scene hiding behind a cushion", while Anne simply said: "I feel sick".
Paul later told Billy his hand felt numb and that he'd been "feeling funny" since the accident.
