I know you're worried, but this is what we were brought here for. To fight and watch one another's backs. I've fought with people that I have absolutely no connection or tie to and I've fought with people that I do. Some things are easier in one and some are easier in the other.
During the last mission I was already placed on a team with people I knew. Others have too just as you and Steve are stationed at the same camp this time. If they wanted us to be completely objective, we'd be placed on teams with strangers. This mission isn't what you remember of your past mission. I'll be okay.
