The synchronized swim in Marigot Bay spontaneously generated. This lack of rehearsal proved dangerous when Andrew was kicked several times on and about the head.
Kully did not participate. He floated like a cadaver nearby.
Warren also did not participate. He was unaware of the goings on until it was all over. He waxed mildly enthusiastic about the possibility that the synchronized swim had been executed in secret, which is why he did not know about it.
Heather also did not engage in any synchronization of swim. She stayed in the boat because she was cold. Allegedly.
