Episode Summary
Lawrence is preparing to sail once again on the SS Lindana. Linda and Candace were too scared to come this time after what happened last time. So was Isabella. This time, Olivia was coming with them. This time, they asked Josie to watch over Perry. Olivia wonders why Maddie couldn't come. Phineas says that Maddie had plans. Lawrence takes the boys and Olivia off to sea. Lawrence clearly didn't pay attention to The Weather Channel, because there was a storm. Olivia questions why they chose today to sail. Meanwhile, Josie is watching Perry like a hawk. She'll make sure he doesn't disappear.
