Radio expert and codebreakerBackground:
You may have thought that the lack of a title in front of his name was a mistake, but it wasn't. In fact, Adrian had had his military rank revoked after deliberately disobeying the orders of his officer and charging out of the secret hiding place they were in in Eastern Europe, while spying on the Russians. Of course, he was the only one monitoring the radios and cracking the Russian codes, so he was the only one who knew what they were saying. They knew the hiding place, and were coming to attack, so he got the hell out of there. Only one out of the 7-man team there died, so he thought it wasn't bad. Problem was, no one else could read the codes to verify what he thought, so his rank was revoked.
He wanted to stay in the military, though, even if his attitude was a bit to rebellious for the navy. However, he was one of the best code crackers and radio operators outside of Russia. The officers thought it would be appropriate to put him on a submarine and send him away when they gave him a 'promotion' or 'second chance.' Hell, he hadn't even seen it coming, he had been that naive. But he was flattered, in a way, that they needed him enough to take him back, even if it was on a submarine and not in a comfy home on the East Coast. And that was how he ended up on the submarine. How would such a carefree, rebellious young man deal with having so many enticing women on board? Only one way to find out...
(I tried to mix it up and make him different, so let me know what you think!)
