After wounding someone, Jimmy immediately shouted to Steven behind him, "Stay alert, I'm going upstairs to check."
Without waiting for Steven to speak, Jimmy went straight up the stairs. The person he wounded was lying on the ground, now writhing and moaning in pain. Everyone reacts similarly after being shot, except for those with fatal injuries.
Rushing to the third floor, Jimmy fired a shot at a room door, quickly put away his Glock, picked up the gun dropped by the wounded person on the ground, and stood against the wall on the stairs.
Only after firing did Jimmy realize that there was another person in that room whom he wanted to execute on the spot. The current situation seemed opportune amidst the chaos. Whatever happens, there would be some reason to clear himself of suspicion.
