So. In our kill team we have:
An Imperial Fist Librarian,
A Black Sheild Tac Marine,
A Grey Knight,
A Vindicare Assassin,
A Raptors Tac Marine (me, squad leader),
An Apothocary of unknown chapter (he only joined us last session so we havent had much time to get to know him yet),
And lastly, a Storm Warden Assault Marine.
Now, our assault marine is starting to become a bit of a problem. In our first mission he dissapeared up a stair case after he had been told to stay with the team, did his own mission which as far as any of us know, wasnt sanctioned or for the good of the Imperium, and somehow appeared behind a shroud of dark energy working on a computer with a dead Alpha Legionary. When asked how and what happened, he was non-commital and vague.
After it happened my character slipped into a coma due to his injuries, (fire really hurts,) and had a vision from what I assumed to be the Emperor who told my character that one of our kill team was going bad.
And now on our current mission, the assault marine was injured by Tyranids. When my character went back to get him, his body had dissapeared from where he had fallen and despite my character searching for him, couldnt be found.
When we later re-grouped, the assault marine came jogging in from the desert with no injuries. When asked how he had gotten away from the Nids, he was non-commital and vague again. And my character also rolled one degree of sucess on his perception test and had a very strong feeling that he was lying and couldnt be trusted.
So, my main question out of all this is; If it comes down to it, what would be the best way for my character to kill the assault marine?
I already have the assassin ready to pop a bullet in his head if I order him to. But if it comes down to a one on one fight, what tactics should I use? His character is very good in hand to hand where my character isnt really that great unless he's wearing his armour. (+10 WS Gauntlets of Xirion.) And whilst my character is pretty good with his bolter, his character would be on him before I could finish him with bolt rounds. I'm pretty sure the Grey Knight would help if I can prove that he's gone heretic. But right now all my character has is a feeling.
Out of game, the guy playing the assault marine has said that there's a good chance his character is either going to get killed by something, or one of the other guys in the team is going to have to kill him.
The guys I play with also play Black Crusade. So even in Deathwatch they dont really work as a team. They all want to be one man armies. Which is very frustrating. An example of this is when my character ran back into the invading Nids to pull the injured Librarian out, and the guys around the table said, "Why are you going back for him? Dont you remember that he's the one who set you on fire last mission?" (I did it because it's this weird thing called "Teamwork")
Really, I dont want to kill him. I want my team to act like a team and stop all this cloak and daggers bullcrap. It's affecting our missions and it's taking up too much of our game time. We have enough to worry about without having to constantly watch our backs from our own guys. But if I need to kill him, then so be it.
