Loki had covered his face with what remained of his clothes and was now using his wires to hold back the mysterious young man that was going to kill Bernard. The moment Loki did so he felt the power the young man held, it took almost everything he had to stop the young man's right arm.
The young man turned around and was unable to locate the source of the wires that were holding his arm. Loki had already hidden his aura from the enemy as this was the very basics of being an assassin.
Seeing as he could not find the source of the wires, the young man broke free from it by the sheer force of his physical body. The moment he broke free from the wires, another wave of wires wrapped around not only his arms but his whole body, and this time they were more durable than the last.
