@FrostedCamel Sam and Kosuke could have a rivalry or mutual dislike for one another that can be highlighted by their personalities or future events. Such as Sam pranking/humiliating Kosuke deliberately in which case will cause Kosuke to retaliate in a similar manner as I doubt he would be the one to instigate things. They could even take it to the boxing ring and involve the others if able.
Sounds like a plan to me, was already going to have Kosuke continue to fuel his hate(Maybe rivalry is a better word?) for the little brat next time he got a chance.
As far as Rolando goes, Kosuke has no clue what to think about him so I was kind of hoping on building his frame this rescue mission. But it won't matter anyway due to rank separation unless we break that a bit.
Kosuke only knows of Drogo that he puts full faith in a supernatural being (Which he thinks is crazy) and that he enjoys to drink and brawl. One of those things he enjoys.
@Deathwatch101 with Marvus and Jack they could both take a mentor type of position, except Marvus would be the caring father kind of deal and Kosuke would be the not very caring mentor only doing it to increase chances of mission success mentor (If that is what you were implying they both take a mentor role? Or Marvus mentors them both, I'm not too sure on that because Kosuke
is experienced so there isn't much Marvus could offer he doesn't already know kind of a deal.). If what myself and RedArmy talked about before still happens however.... Jack and Kosuke will be taking a very different turn in interactions.
For
@Akashi , Kosuke has seen Erika in action and even kind of looks up to her just like he does the Major. Some sort of camaraderie/friendship could be possible there if Erika were willing.
For
@EmperorsChosen I think our two characters (if yours doesn't die) won't really get along because they're so different but so alike at the same time. Sorry.
Those are my two cents on the characters.
Also,
@Detective Zero needs to come back and add his character into the mix.
