Robyn and Ed have a beautiful home on a quiet street with a pool out back that Christopher can play in. The property is bolted down so tight, Christopher can never elope. The front and back doors have key locks on the inside as well as the outside. The garage is locked. There are locks on all the sliding doors. The house has an alarm system, with a chime function.
When Robyn was living alone with Angela and Christopher, he was nearly impossible to care for, and as a single mother she felt she had no other choice but to put him in a place where other people could take care of him 24 hours a day. He got kicked out of day care because he bit other children. They had to put a harness on the bus for him, a five-point seat belt, because without it he'd run up and down the aisles, hitting students and even the driver. Christopher split his weekends between Robyn and Walt and stayed at the group home on weekdays.
When Robyn and Ed first saw Walt after the incident, it was on the dock, as he stepped off the coast guard boat; he was sunburned and babbling like a child. They didn't have the energy to confront him, to yell at him, to tell him they had been right. They were just happy that Christopher was alive.
Three weeks after he comes home from the hospital, Christopher is named grand marshal of the parade at Disney World. Robyn and Ed make sure to keep a sharp eye on him the whole time and to hold his hand. He gets a Florida Safety Hero award. He gets to stand on the bridge of a coast guard cutter and pretend to drive.
