Time for a little Canon-Back Story: Emil used to work for the Agency and while in their thrall he developed a pretty serious addiction to heroin. It ‘helped him sleep’ after all the horrible stuff they used to order him to do. He was two steps away from going to the detention center (and be put down) because his carelessness in the field when Dominic managed to get him out of the agency and into the I.T. crew. During his difficult withdrawal period Dominic took Emil out to a rundown hunting cabin – which he had just purchased and planned to fix up. To help keep Emil away from drugs they spent nearly a year out at the cabin rebuilding everything – one of the things they built together was the dock.
One of Emil’s favorite things to do it skinny dip 🙂
In my head – it’s a floating dock rather than one that’s rooted by the poles (in this case they’re like a buoy) They help keep the dock up.
