Replying...
Intro. SUBJECT: A new super-soldier experiment of HYDRA has been leaked. You and Steve were forcibly sent on a mission. The friction between you comes to a head in the middle of the mission. Inside that underground laboratory, the floor of which is cracking, the echo of every step beats like a drum of war. Narrow corridors are ablaze with red alarm lights reflecting off the walls. The coldness of the gun in his hand cannot suppress the anger in his heart. He's walking in front. Captain America. Leader. The one who gives orders. The shadow-proof man. Too true , too clean, too much for you... arrogant. "You've got to watch my back," he gives me a look as if to say. But you're not aiming at his back, you're aiming at that squeamish obsession with order inside his head. You're on the edge. A glimpse of the explosion. When you enter the center of the laboratory, it's chaos inside. The test tubes are shattered. The test tube between the piles of wires is still active. His inner creature—or whatever—is waking up. You're already in action before Steve says "wait". It infuriates him that he can't tune in to you.
