My son got into a fight at school because another boy wouldn't stop calling him his "brother.

"And you agreed," I said. "To falsify records. To let me believe my own son died."

"I falsified the death certificate," Renata admitted, her voice barely audible now. "I had access, and Foster made promises about supporting us financially that I was, to my everlasting regret, willing to believe at the time. I want you to understand I've spent eight years telling myself a story where this was somehow a kindness instead of exactly what it actually was."

"Where has Foster been?" I asked. "All these years. He's been living with me the entire time."

"He's been living with both of us," Renata said. "Splitting his time. Business trips, he told you, I imagine. He told me the same thing, honestly, about visiting an aging aunt three states away."

I sat down slowly in the chair beside her, working through eight years of a marriage that had apparently existed alongside an entirely parallel life I'd never once suspected.

"Silas," I said, looking over at the boy who shared my son's exact face, "do you know any of this?"

He shook his head slowly. "Mom just told me my other family lived far away. I didn't know I had a brother until Milo's last name matched the story she told me once, by accident, a few months ago."

"That's how the fights started," I said, understanding finally settling into place. "He recognized something."

"I think some part of him always suspected there was more to the story than I'd given him," Renata said. "Kids notice more than we give them credit for."

I called Foster from the school parking lot, my hands shaking so badly I nearly dropped the phone twice dialing.

"Naomi," he said, his voice carefully neutral in a way that made my stomach turn considerably harder than his actual words did. "Is everything okay? Is Milo hurt?"

"Come home," I said. "Right now. I know about Silas."

There was a long silence on the line.

"I can explain," he finally said.

"You've had eight years to explain," I said. "You're going to do it today, in person, with Renata and both boys sitting in the same room. I want every single detail, and I want it before I decide what happens to this marriage."

Foster arrived at the house an hour later, his face gray in a way I'd genuinely never seen before, not even during the worst days of my recovery eight years earlier.

"I panicked," he said, sitting across from me at our kitchen table, Renata and both boys waiting in the next room. "The medical bills from your delivery were already enormous. I was scared of raising two children I didn't feel financially prepared for, and Renata offered a way out that felt, at the time, considerably less permanent than it apparently turned out to be."

"You told me our son died," I said. "You let me grieve a living child for eight years."

"I know," Foster said. "I've hated myself for it every single day since, and I still let it continue, which I understand makes the apology mean considerably less than it should."
