Walt spun in every direction, trying to spot the small white face and the dark-brown hair.
But he was gone.
Walt wiped his eyes, took a breath. He's gone. It was a thought as dark and fathomless as the ocean itself. At that moment, he couldn't see it any other way – Christopher was dead. So Walt stopped yelling and shivered as a trail of bright green phosphorescence floated past him. He stared at it, amazed by its arrival, the only color on the sea, passing behind him like lights beneath the water. He told himself it was probably peaceful, told himself that Christopher just got tired and finally let go. Just slipped away under the sea.
But Walt's mind wouldn't fully accept that. Christopher was a terrific swimmer. He had nine lives, Walt liked to say. Maybe he was merely playing a game. Maybe he was floating, just beyond where Walt could see. Maybe he just wanted to be alone for a while, like he sometimes did.
Christopher had wandered off so many times, Walt learned to expect he would always be okay. "Eloped" is the word used to describe the way an autistic person sometimes wanders off – is there one second, then vanishes.
Christopher had eloped at the mall, at the hardware store, from Walt's parents' house, and after a search they would often find him playing in water. At first it was the lake in their old neighborhood, then the retention pond at the bottom of the street – the police had sent a helicopter to search for him. Then it was the neighbors' pool: floating on his back, naked. The neighbors called the cops, who came and pulled Christopher out and saw the silver chain bracelet on his left wrist with his identification and phone number.
Once when Christopher wandered off, the police searched for him again, and half an hour later, he turned up in the fountain at the Oviedo mall. Christopher had walked across a busy intersection, crossed through six lanes of traffic, had navigated the winding road back to the parking lot at night. He had taken his clothes off and was splashing beneath the falling water in his underwear, his feet brushing the pennies people had tossed in to make a wish.
After each of these episodes, Robyn would fume at Walt. She no longer trusted him. She and Ed held their breath whenever Christopher was with Walt. When Christopher was with Robyn and Ed, they never let him outside without maintaining physical contact. But Walt wanted Christopher to experience the world like a regular boy, wanted him to walk the stadium stands without holding his hand and feel the beach sand and breathe the air, wanted him to make choices.
Walt couldn't even bear to call him autistic, to label him that way, and his voice always cracked when he talked about his "little buddy." He took the good days, swimming together at the Y, sitting together in the front pew of church, eating at McDonald's without incident, and weighed all of that against the tantrums, the outbursts, the moments in which his son would lunge at him, out of the blue, and sink his teeth into his arm. That's when Walt would sob. He'd lament having to shout at Christopher, asking him why he'd attack his own father. For every good day there was always some kind of reminder of the bad.
But now he was gone. They shouldn't have come out to the beach, he told himself. He should've rented a movie and spent the day at home. He could never face his own family. He wouldn't know what to say to his mother and father, to his daughter, to the coast guard, to Robyn and Ed. The guilt, too, the realization that he had been responsible for his son's death.
He decided that he should take his own life. It would be easier. Bawling, his tears mixing with the salt water on his face, he took a deep breath, exhaled, and slipped like he imagined Christopher did beneath the surface.
But there was Angela. He had almost forgotten about her. He kicked his legs and came up for air, expelling a mouthful of water. She needed a father too.
