MC 100% is an unreliable narrator, just by the fact that she forgot a bunch of stuff (Confirmed by Lane)
I completely forgot about the knife, BB does not seem to have any physical injuries that are fresh. UNLESS the injury is on his face, I had assumed he covered it because in Iraq he was injured and just didnt want us thinking he looks bad or scary. BUT what if is was us what attacked him, and he doesn't want us seeing the wound and realizing it was him?
MC clearly doesnt know what happened but knows enough to not wanna go back to it, this event involves blood, BB, a broken helmet and a bloody knife.
But what if we were attacked? what if that look covered knife was used on someone else, and BB happened to step in and unfortunately kill the eprson attacking us?
IDKKK AHHHHHH i wanna know everything this game is so good!
