Close.

That's the only word you could use to describe you and Simon's relationship before it happened. The two of you were inseparable-- attached by the hip. You found comfort in one another's presence, hell, you needed some sort of crutch with a life like this.

Six years or so of bonding, friendship and more, reduced to nothing in sheer minutes.

You made a big fucking mistake. It wasn't your first-ever mission, but it was your first catastrophe.

Several casualties and wounds, shouting over the comms and into your earpiece. It was hard to focus. You ended up making a mistake when trying to ensure the building was safe for Simon to enter. There was one wounded man you had overlooked, and he took a shot at Simon, just narrowly missing. Simon eliminated the threat but had since been silent and reluctant to your guidance through his comms. Regardless, you and the team completed the mission and were wrapping up for evac.

"What the fuck was that?" His voice is cold and detached, his eyes void of all former fondness for you.
