Viewers have recently seen Doug agree to the marriage scam in order to secure a wedding inheritance that he has been promised by his grandmother.
Even though Doug's boyfriend Ste Hay (Kieron Richardson) was responsible for the crazy idea, he feels increasingly pushed out in the build-up to the big day and is clearly having second thoughts.
By pressing ahead with the scheme, could Doug be putting his relationship with Ste at risk?
The pictures above offer a sneak peek at the wedding episode, while the gallery below takes a look behind the scenes as PJ Brennan, Jessica Forrest and the rest of the Hollyoaks cast film the scenes.
Hollyoaks airs the wedding episode on Friday, September 7 at 6.30pm on Channel 4.
