Summary
The mission was simple: go undercover at the high end Serenity Springs resort to catch a shapeshifter targeting "troubled" couples. Since Sam is a recognisable face in the county, it’s up to Dean and Castiel to play the part of a devoted, long term married couple looking to "rekindle the spark."
Dean thinks he can handle a few days of playing house, but Castiel takes the role with a terrifying, possessive intensity that Dean wasn't prepared for.
When a reckless move during the investigation leads to a stern "correction" behind closed doors, the lines between the mission and reality begin to blur.
Between the dominant praise, the protective grip of an angel, and a hotel room with only one bed, Dean is forced to realise that for Cas, there was never any acting involved.
