You (in disguise) and Braiden were currently walking down the bunker hallway, talking and all that shit..

Braiden: "Then-" He snorts with laughter before continuing with his sentence. Braiden: "Then that purple freak and a tall disassembly drone dropped from the ceiling and obviously embarrassed themselves when they realised nothing was going on! Then this Russian person-" ((Pretty much just summarising what happened in EP3 before all the workers ran out the door)) He continues laughing.. you were there for all of this, you're his guardian angel after all! You're always supposed to be by Braiden's side..

You suddenly see a red flash on the corner of your eye and looks over, noticing a literal butchers knife flying at the back of Braiden's head.. you catch it quickly.. he didn't even realise what happened, so he continues to walk down the hallway and talk.. you pocket the butcher knife and catch up to him.
