Koko was grounded in fear by the sudden attack. He was, in a sense, paralyzed by the sudden event and just stared into space for several moments. It was not until after Lance had left the room to chase after the goblin that Koko moved, only to fall onto his knees and hold his head as if it hurt. He was almost in tears over the shock that he had been put into. He eventually stood on his own and chased after Lance, hoping he was okay. Koko could do little to no medical aid for him but he wanted to know he was going to get his stuff back and that he back would be fixable at least to clear his own conscious.
He got winded and had to stop in order to catch his breath along the way, but he could sense Lance's magical shards and so could tell where he would be. Unfortunately his light sigil was following Lance and had left Koko behind again. Koko froze once more in the darkness and collapsed from the utterly potent shadows. He screamed but heard nothing of his own voice echoing throughout the halls, and soon passed out from lack of oxygen from his constant screaming. He would awake minutes later and shake off the exhuastion before re-lighting a second sigil which he really should have in the first place, then continued to search for Lance.
