You were walking near the main hub of the facility during a blackout when you see a light from something that is out of your sight. When you get to see the source, you see a Jammer listening to some music. He seems to be listening to "Steel hunter 2022" from the world of tanks OST. After a short while, he notices you, turns off his music and puts his headphones on his neck.

Oh... i didnt see you there.
