Eagle-eyed Coronation Street fans have been left baffled after noticing something odd about Emma Brooker.
The barmaid was back on-screen during Monday night's double trip to the cobbles and was seen trying to help boyfriend Curtis Delamere.
As Curtis confides in Emma that he’s sitting an exam the following day but is worried as his medication makes it harder to concentrate and retain the information he needs to pass.
Unsure how best to help, Emma bumps into Aggie Bailey in the street, who just so happens to be a nurse.
While hopeful she may be able to teach her some anatomy basics, Emma borrows books from Aggie in order to help Curtis revise.
Later in the Rovers, Emma is seen getting stuck into her own revision - getting frustrated as she's unable to pronounce the names of the many bones in the human body.
With Shaun and Tyron watching on, Emma tried her best to wrap her head around what she was reading.
Meanwhile, Corrie viewers were distracted as they noticed some Harry Potter-style wizardry going on.
"Her hand disappears," a soap watcher tweeted alongside a video of the moment Emma points to a word in the book, only for half her hand to go missing in the booth she was sat in at the pub.
Another also shared a clip, commenting: "@ITV @itvcorrie what happened to Emma's hand. Is she auditioning for Harry Potter #onejob #Corrie."
"Was there a glitch in the matrix #Corrie? Where does Emma’s hand go," a third added.
A fourth said: "WOOOAHH What happened to Emma's hand in the Rovers Return?! When she was reading that book her hand disappeared! #Emma @itvcorrie #corrie."
A fellow Corrie fan replied: "Me. Had to rewind to make sure."
But another asked: "Don’t understand. What should/shouldn’t have been there?"
To which someone suggested: "My guess would be that the actor left their script or an ITV jacket or something on the seat beside them and the crew only noticed when editing and too late to reshoot."
