As if Kurt's heart was not beating fast enough, the growl and flinging of weights sent it up into his throat. Instead of simply landing, he kept moving, rolling into a crouch, bounding from that pose into a backwards handspring, then he took a good sized step back in addition. Just in case. "Gott in Himmel!" He exclaimed shallowly as he danced away from those claws, his eyebrows settling high on his forehead in surprise. He quickly held both hands up, a sign of surrender as he kept on the balls of his feet, ready to spring away if necessary. "I am sorry! I thought I was helping!" He tried to insist. True, he was quite skilled with swords, but he was currently unarmed and he seriously doubted that even his best blade would stand up to those claws.
He winced as the heavily weighted bar crashed to the ground and then the wall, ripping a good sized hole in it. Still attempting to diffuse the situation, Kurt pointed to the barbell, cracking a quick, nervous smile. "It is my fault! I will pay to have that fixed! All is gute! I did not mean--I thought you would drop the weight, und I was afraid for you." He spoke rapidly, trying to both explain and diffuse the situation. "I did not mean to anger you so!" He added quickly, cracking another nervous little smile.
