There was actually a reason for him not sealing the door, it was kind of the only way out of the room. Besides the ventilation shafts, but he was way too big in his armor to go through the ventilation system. Now, LeeRoy heard the hissing of the door, and honestly he was hoping that for once his taunting had worked. When he saw the armored guard stepping in his face distorted into a frown. This obviously wasn't the guy he was expecting to come through the door, just another pawn on the chessboard, but then something awful happened.

"Is that?" Damn, miscalculation. Not at the taunt, taunting never seems to work. It's like everyone in the multiverse is an emotionally static individual. "That's a SWAT breach." No, the miscalculation was the typical SWAT breaching tactics. Through the door a flashbang came through, the noise wasn't the issue here his suit was thick enough to shield from ear splitting sound, it was the flash of light. When it exploded it caused his eyes to go fuzzy and be flooded with little circles of white light. In the haze a figure moved forward, LeeRoy brought his gun up and fired with his eyes closed. Closing his eyes would allow them to adjust faster than if he held them open. He knew he was facing the door so he wouldn't deviate much from his firing sights. Though he was blinded he could still kill at least one of the poor unfortunate bastards. "Usually the bad guy enjoys fighting the protagonist one on one." LeeRoy fired off six shots from the rifle into the doorway, totally blind to their flight path. Fortunately they were fired fast enough and close enough to the door that they shouldn't miss.
