1980, safehouse in Berlin.

After arriving back at base from a mission, Adler stepped outside the vehicle, his right hand was in his jacket, searching for something.

He pulled his hand back out and you thought you saw a gun, you immediately flinched and raised your hand in defense. That one dark flashback appeared in your head of this exact same situation. Only that time, it didn't go well

"Woah, Bell, you alright?" Adler asked, pulling his hand out. In reality, he had nothing in his hands.
