Coronation Street fans are starting to worry Jan may not be who he seems.
The builder recently arrived on the cobbles and was hired by Gary to do some work for the business.
He seems to have charmed Eileen Grimshaw and the pair obviously have an attraction to one another.
After Pat Phelan's reign of terror, viewers were left hoping Eileen would find happiness with Jan, but is he just as dodgy as her serial killer ex?
In Monday night's episode (April 22) Seb Franklin met a young girl named Alina whilst out on a job in a nail bar.
The owner of the nail bar, Rachel, obviously knew Jan as she was originally looking for him to do the work and she mentioned Jan as Seb was leaving.
The young builder got to see Alina again in last night's episode (April 24) when she returned his wallet to him.
He offered to take her to Speed Daal for dinner but when they arrived, Eileen spotted them and Jan didn't look too happy to see Alina and quickly turned away.
Alina saw Jan and Eileen and told Seb she wasn't feeling well and had to go.
This left viewers with a few questions. Why did she change her mind so suddenly? Does she know Jan?

Fans have already come up with a few theories about how Jan and Alina know each other.
Jan is Alina's father
Some believe that Jan could be Alina's father, despite him telling Eileen just moments before that he had no children.
I wonder if Seb's date is Jan's daughter? #Corrie
Jan is involved in human trafficking and slavery
It has been widely speculated that Jan could be involved in Coronation Street's human trafficking and slavery storyline.
Jan was involved with Pat Phelan
Although unlikely, it's possible Jan knew Phelan. After all they both worked in the same trade, but was he involved with the murderous builder?
Coronation Street is on Monday, Wednesday and Friday at 7.30pm and 8.30pm, with an extra episode on Thursday at 8.30pm on ITV.
