Parting from the crowd Tirren saw a brown haired student in a ratty jacket run towards a wall and grab another student and use her as a shield. Curious he glanced in the direction the man had run from, seeing nothing but a multitude of students he realized their was only one way to satisfy his curiosity. 
At least there was something to catch his interest now Tirren thought as he walked toward the brown haired student and his blue hooded human shield. If anything Tirren knew that it would be an interesting conversation one way or another. 
"So what's with the whole human shield thing?" he questioned as he approched from the left of the two.
