As the storm approached, an unlikely figure took the helm--the smaller of the two Saber Servants and the one that had absolutely no idea how to appropriately control a ship. The pirate captain would find attempts to dissuade her from this about as much use as talking to a wall as she took position beside him, a determined expression on her face and drawing a deep breath.
"Men, a storm approaches and yet it must be a blessing in disguise! Umu, divine blood flows in my veins and it can only be so! This storm is clearly a blessing of Neptune in disguise, sent to bring us swiftly to our destination! And so! We shall not falter or slow down! We shall go faster into this, and use it to our advantage! We shall ride the storm!"
Now was probably a good time for anyone sane to realise that the ship was now rather directly under the control of someone who should very much not have been in charge of a ship--as realised by the blank-faced alchemist, who, sturdy ship or not, was disappearing below decks.
