-Five Minutes Earlier-

"By the way...." Lee said slowly taking a step back. "Did I tell you my rule no. 3?" Lee asked taking yet another step back the grin on his face still visible beneath is dark hood. "Improvise!" with a twirl of his staff he slammed one of the ends resembling a wrench down causing both ends of the weapon to suddenly release its smoke bombs. Plumes of thick dark smoke quickly filled the hallway startling some of the students present watching the scene. 

Good the scene was now completely covered in smoke. With the students moving about in confusion he had to work quick. Pushing the door open wide enough to look suspicious. Before swinging his staff at the vent knocking the grate off and allowing it to hang by one screw. With his work done Lee quickly and silently began his next move as the sprinklers went off the sound of his staff retracting was heard with it being returned to his back. 

-Present Time-

"Crap" He muttered under his breath struggling to return the book back into his coat. Being thin had its advantages but it still sucked being trapped in such a tight space dripping wet. At least on the bright side the book was not damaged nor even damp thanks to the inside lining of his coat. Then he heard it, sounded like something had just infiltrated the vent systems. "Time to go." He realized suddenly before something that he would not prefer to happen to him. 

Ever so gently Lee opened the door to the locker near where he used the smoke bomb.  He had been hiding inside it the entire time while the others took the bait and left the scene. Thieving Rule No. 4: Always create a distraction. Even if it meant for his distractions to have distractions. Kat took the bait and entered the classroom and by the sound of things she's not even on this floor anymore. Though he didn't expect several others to join in on the hunt oh well that makes it even more fun. Pulling his hood down to look less suspicious Lee took his leave from the hallway. 

"Now to go the one place they would never dare to look." he said already pleased with how this was going. Slipping down the stairs Lee made his way to the ground floor.
