The flames draw back form the team, and part when they get close. From the other side, a long corridor is revealed. From it comes an ominous whistling.
Martin turns around surprised, seeing the rest of the team there walking through the fire, "wth, what took you guys so long, stop yelling my name and come over here then and can you bring some light up in this place Naru, some idiot blew out the lights."
"Get of me, what's wrong with you", Martin says as he pushes Naru away, "Thank god, the lights are finally back on, I had to fight that gun man in the bloody dark, that **** head threw that fire ball at me, I'm gonna get him back for that". Martin then turns around and looks down the corridor to see what is ahead of them now that they have light.
The corridor now seems normal. The feeling is completely gone. The firewall has completely vanished. A staircase is ahead that wasn't there a moment ago.
At the top of the staircase there is a small observation room. It has a large window overlooking a wide expanse of snow. It has no visible exit besides the staircase used to get there. Standing there, looking out the window, is the gunman. He has his arms behind his back and is unarmed as he looks at the snow field.
He spins lightning fast and grabs Martins arm near the shoulder. In a different situation it would look as if they were greeting each other. He twists the arm with superhuman strength and brings Martin around as a shield against the others. He pits his other hand at Martins throat, where he could snap his neck.
