"So we need to be home the rest of today, but Dad's friends - unless they're suspicious Controllers? - aren't going to go prowling upstairs uninvited if we're short with them at the door. Me and Andi and Robin are all officially here and can take turns being downstairs and awake to answer the door while everybody else naps so they can stay up late. After ten p.m. nobody is going to go bother some teenage girls whose father just died, so we can go then, pigeons aren't great for at night but we'll have city lights to go by and should be able to manage. Orcas will be in a tank open to the air, with any luck we can find one by itself so Trouble can calm down one hundred percent of the whales in the tank for us."
