This time, her sword sunk deeply into his side, setting him off balance and causing him to drift towards Killian. Even though it was likely to fall, its claws were out, ready to strike.
"Emma!" Snow shouted, moving towards the demon to assist Killian. For the moment, the portal was free and clear; if they worked quickly, they might be able to get Jefferson there in time. "Go!"
