I just imagine like the S/O and either McCree or 76 taking a break from heavy work for an extended period of time and going on a road trip through Route 66 and further. Him driving and the S/O playing on the guitar in the passenger seat. By the campfire they play on the guitar something like Your Hand In Mine by Explosions In The Sky, generally take their mind of work. They go to sleep in the back of the van, where they just cuddle to sleep. Next morning, they have all the time in the world.
