Conna'Cel tried to dodge the attack, and was hit with a glancing blow. Still, it left enough force for him to spiral out of control and force him to land roughly on the ground to stabilize himself. He skidded on his feet for a few feet before stopping to a halt. 

He took a moment to recalculate the creature's movements, but by then the beast was already killed. He then took the time to scan it now that it was visible, noting everything he could gain from it and storing the info for later reference. Ignoring the arguments in the background, he watched as the mysterious girl Marianne take the corpse and leave, then put away his metal wings. The time for flight was over, and the time for escape continued. 

As he was about to exit through the doorway he had found earlier, he noticed another opening that definitely was not there before. The painting above it was negligible, though, and he ignored it. Moving past the porcelain girl, he went up to the staircase, looked up, and started scanning the path for potential dangers.
