Ep. 7 Ray of Despair, Ray of Hope English (Dub)

The crew send Senku, Soyuz, Kohaku and Gen to find the islanders. Ryusui finds Suika stowed away on the ship. Ukyo and Ginro find statues underwater and realise they couldn't be from the petrification event 3700 years ago since the island was uninhabited before the astronauts arrived, so these statues were petrified much later. Losing radio contact Soyuz and Gen find everyone on board petrified into statues, except for Suika whom Ryusui saved by throwing her overboard.
