Coronation Street fans have been playing detective about Courtney Vance's true motive in starting an affair with Aadi Alahan - and are convinced they've uncovered something that could have a huge impact on Dev. Viewers of the ITV soap have been growing suspicious about newcomer Courtney, played by Stephanie Davis, who caused chaos on the cobbles by starting an affair with Aadi (Adam Hussain) not long after she arrived. Courtney moved to Weatherfield with husband Darren (Ryan Early) who was going into business with Aadi's dad Dev (Jimmi Harkishin) but started a steamy affair with impressionable Aadi soon after meeting him.Things moved quickly even for soapland, as Dev and Darren both discovered the affair, Courtney moved in with the Alahans, and Darren served his wife divorce papers.
