They spent the rest of the morning watching the noble guests play beach games then went for a swim before relaxing on the beach with glasses of juice. Or at least Max went for a swim.
As it turns out, Nico does not float. At all. So, despite being waterproof and able to absorb oxygen from the water, playing in the deeper parts of the lake was not for her without specialized equipment. She did have a lot of fun in the deep water though, walking out to the center of the lake to admire the view out of the station through the transparent panels.
All morning long, Max sensed that something was not right, but when he listened to the thoughts of those around him he didn't find anything strange or threatening. He was beginning to think he was just being paranoid, the way the threat seemed to keep changing directions throughout the morning, but it was too persistent to be nothing at all.
