Right now, he couldn't think straight.
With the guard's pistol nestled in his hands, Gabriel was on edge as he crept through the darkened hallways. He carefully loaded the bullets into the chamber, at the same time easing his breaths. The murders he had committed earlier gave him a certain rush, and since then, the world was naught but a hazy blur. His eyes watered involuntarily as he stalked down the long hallway, looking around to see where he was. Judging from his position, Gabriel concluded that he was standing in the western part of the castle. His main objective was to find a way into the central tower, where Dracula was to be for the night. Then he could even the score, and repay the heartless fiend for all the years of suffering he had inflicted upon him...
The immediate sound of clattering weapons and heavy boots bounded down the corridor, in his direction. He looked around, trying to find somewhere he could escape to or hide, at best. Thinking quickly, Gabriel dashed into one of the old rooms at the far end of the hallway. It was dark and it smelled horrible, but at least it provided him with shelter for the time being. He took a deep breath and held it, shutting his eyes tightly as he did. He thought about shooting the guards, but he couldn't do it, for risk of being discovered. If two dead centries were found lying in the middle of the corridor, then the others would obviously know that he had been there, and was headed for the crypts. They would know exactly where he would be, and he couldn't afford that chance.
The sounds of rough voices came closer and closer, nearing the room door. He dared himself to look out, and responding against his better judgement, he did. As he peeked through the keyhole, two brawny bodies completely passed him and dashed farther down the hallway, still shouting. He sank down and breathed a quick sigh of relief, his hand still clutching the handle of the pistol.
He opened the door and slinked out of the room and back into the corridor, looking both ways to make sure it was safe. To his relief, he saw no more guards or hear any more voices. From what he knew about the castle's blueprints and things he had heard from long-dead prisoners, he concluded that he would have to go deep into the crypts in order to get to the other side and the central tower. Gabriel ran down the hallway as fast as he possibly could, grabbing a torch as he descended into the darkness.
