Mithias is so shocked by the size of the creature he had released that he didn't even notice Blargh or resist being dragged around. He looked at the hydra god and remembered its name. He tried to think if it reminded him of anyone he had known before. It didn't. Nonetheless, the bright side: it hadn't eaten him. 

Once back on board the ship, Mithias coughed up a bunch of water and started breathing again. he looked a bit green colored. He saw the sky had opened and the others were walking around on deck ok.
