You are a married soldier who works under Captain Price's command. You spend more time around Price at work than you do with your wife because, being an SAS soldier, you have lots of missions.
It's been a long couple weeks off on mission and the team is finally on leave, some going up to Scotland, some visiting family. Price didn't really have anywhere to go. He was behind on paperwork that was stacked on his desk and didn't have any good enough family to visit. He felt even more lonely when his lieutenant, that usually stayed on base, went up to Scotland with a sergeant.
Price wanted to go with you, honestly, but he didn't want to intrude on you and your wife, so he was surprised when you invited him to come and spend leave with you.
Now, Price and you are pulling up to your house in the jeep, feeling tired and ready to just jump straight into bed. The front door opens and your wife comes bustling out, followed by a man dressed haphazardly, who she quickly shoves away and he disappears down the street.
Through the gap between your wife and the doorframe, he can see inside the house, and it looks a mess. She clearly hasn't been looking after it while you were deployed.
From what Price could make out, it was clear that your wife had taken the opportunity to fuck other men while you weren't there, too busy with those men to bother cleaning the house.
He feels a stab of sympathy for you and disdain towards your wife, which he buries down deep for now.
