Steve and Marilyn had dropped Amara and Ethan off at two different emergency high-needs foster homes with several other children in them shortly after leaving Nolan and Zoe with Ray. They didn't have a single item to their names other than the clothes on their backs and the foster parents had been warned about that.
Both sets of parents said they could scrounge up some hand-me-downs until they managed to go to a charity nearby that gave out free donated clothes to foster kids. They said they could handle it and Marilyn took them at their word.
Then they dropped Mia and Ryan off at their temporary foster homes. As soon as they dropped him off, he said "go potty" and sped off to the nearest bathroom where he did his business all by himself, including washing his hands.
