"Shit." The curse left Sinjin without a thought, immediately moving as he had been trained to. so while the ridiculous battle cry was startling, Sinjin still moved to the defensive. Because Bear was what Sin could only think of as some kind of modern-day berserker.
Sin kept a hold on the knives, only remembering at the last moment they were testing. So he let Bear do his thing for the moment. Even let some chest impacts happen. Keeping his hold on the knives when he would have thrown them normally. Hell, normally he'd have his constructs up by now. But the point was testing this armor, not his own armor.
When the hits came to a stop Sinjin shook out his limbs, eyes glinting dangerously as he eyed up Bear. "You and your fucking elephants. I never said you could have a pet, and I told you to go ask your handler for a pet elephant. Let them tell you no so you can deny them your ridiculous videos," Sin huffed with no real bite to his words. And, the entire time he spoke, he threw. He only had a few of the throwing knives - really throwing knives sucked in actual combat because you ran out of them and had such a short range. But once they were gone, Sinjin just summoned his psionic knives and threw them. Hitting every part of Bear's armor he could manage without pausing in his words.
