"Jace." The shadowhunter replied, as he stepped into the centre of the room. Relaxing into a ready stance.
He'd trained for years with the best at the Institute. To fight beings a lot stronger than him. However, for that he triggered his runes. Runes he didn't need to use for this fight. He could normally tell when someone was something other than human. And, knew that he wouldn't need the extra strength and agility for this.
He briefly considered letting Marcus come to him. But, he never was one for patience. And, quickly went on the attack.
