Homare suggest to explore the island because its too long and no one came to rescue them and she also want to get prepare for upcoming summer and winter. So she want one person to go with her but all three of them volunteer to go with her.
Homare choose Mutsu and went with her. They found dock for boats but no one used it in a long time.
Mutsu asked to Homare that why she picked her. She replied that you have a deliberate nature and adapt quickly.
They worried about two of them. But they found another two girls are following them.
They made bed with the nest and slept on it.
They decided to go 1000 foot in four direction to find valuable items. One of them found broken house which is of no use. Homare found a useful tool out of it which is in bad condition.
At last they found a smoke and episode ends here.
