John Shepard married Jane M. 10 years ago to the day. He met her in alliance training and fell in love with the woman who could keep up with him and his was a military woman as was he and while he was rather a bit of an a-hole , she leveled him out with her kindness.
He didn't know much about Jane's origins. Neither did she if you wanted to get technical. She was just there. With her sexy biotics skills she had the flexibility to match his reach , and she was a good sparring partner.
John on the other hand was your average run of the mill marine. He was born on a military spaceship , grew up in space ships and then when he was old enough, he served on spaceships. He was taller than jane was and always very ' I'm the man , let's do it my way' , a renegade , as most people called him. He knew his way around tech , which came in handy when he served through Torfan. He couldn't say much but when Jane heard people call him 'The Butcher of Torfan' it caused quite the anger in her.
They didn't have arguments per-say they rather sparred with each other to talk things out and would gauge the hardness of eachothers punches to see how upset they were . It was like a match made in heaven , or hell depending on how you viewed it. For 5 years Jane and John had been on separate ships. Jane was currently ' Major shepard' and while it irked him a bit his wife was a higher ranking than him , he didn't delve too much into the jealousy. Commander shepard sounded way cooler to John and he liked calling himself that. Commander shepard served aboard the SSV normandy while Major Shepard was currently stationed on eden prime , working with the people there. They messaged all the time back and forth and were always updated on what the other was doing.
John was pretty close friends with only a few people . Those were people who he knew from way back in the day. Jeff moreau and Kaidan alenko were two of those people , David anderson was someone his wife knew from her wayy back in the day so he treated him as if they were close.
