My sister-in-law announced she was having twins at her baby shower.

The screen on Aaron’s phone glowed with the harsh, sterile blue of a PDF invoice.

Caleb leaned over the kitchen island, his hands planted flat against the granite. His knuckles were bone-white. I stood beside him, reading the lines Aaron was frantically scrolling through with a trembling thumb.

The header bore the name of a private fertility institute located on Michigan Avenue in Chicago. The date of the initial consultation was eight months ago. The line item dated three months before the baby shower wasn't an ultrasound receipt or a routine prenatal bill; it was a non-refundable deposit of twelve thousand four hundred dollars for a donor-egg and embryo transfer protocol.

Beneath it was a signed payment agreement. The primary cardholder listed for the transaction was Gloria Henderson.

The co-signer on the promissory note was Natalie.

"Aaron," Caleb said, his voice barely a rasp. "What is this?"

Aaron didn't look at Caleb. He turned slowly toward the living room, where Natalie remained curled on the sofa, her face buried in her knees. Her shoulders hitched with violent, silent sobs.

"Natalie," Aaron said. His voice was terrifyingly calm, stripped clean of the exhausted warmth he usually carried. "Look at me."

Natalie didn't move.

"You told me we conceived naturally in July," Aaron said, walking into the living room one deliberate step at a time. "You told me we got lucky after two years of negative tests. You told me the doctor at Beaumont was shocked when they heard two heartbeats at twelve weeks."

"Aaron, please," Natalie gasped into her sweatpants. "Please, just let me explain—"

"Explain what?" Aaron shouted, the sudden roar of his voice shaking the framed wedding portraits on the wall. "Explain why your mother paid twelve grand to a clinic three hundred miles away? Explain why there are text messages from March where she tells you, and I quote, *'If we do two, we double the support pipeline from the family'*?"

A cold sickness rushed through my veins.

I looked at Caleb. He looked as if someone had struck him across the face with an iron bar.

"Double the support pipeline," I repeated, the words tasting like copper. "That's what she called her own grandchildren."

Natalie lifted her tear-streaked face. Her mascara was smeared in dark streaks across her cheeks, and her skin was blotchy and pale. "Aaron, you don't understand how desperate I was! We’d been trying for twenty-four months! Every month was another negative test, and Mom said... Mom said you were too proud to get tested, that you wouldn't want to spend the money on treatment because you were already working overtime—"

"I was working overtime so we could afford to start an IVF fund *together*!" Aaron yelled, his chest heaving. "I worked seventy hours a week at the depot! I missed holidays, I missed sleep, I missed dinner with you every single night so we wouldn't have to go into debt!"

"She said she would gift it to us!" Natalie wailed, clutching her belly. "She said Dad left her a contingency fund for family emergencies! She told me it was my early inheritance. She said it was our secret so you wouldn't feel emasculated!"

"And then what happened, Natalie?" I asked from the archway, my voice cutting through her hysterics like a scalpel. "When did the gift become an invoice?"

Natalie looked up at me, her eyes darting away in shame.

"The day after the confirmation scan," Natalie whispered, her voice shrinking into nothingness. "She... she brought over the promissory note. She said the money from Dad's estate had run short because of Caleb's wedding years ago. She said if I didn't help her recoup the twelve thousand dollars through the baby shower and the family, she’d call Aaron and tell him I went behind his back."

Caleb stepped into the room. He didn't yell. He didn't gesture. The passivity that had defined him for twelve years of our marriage seemed to have collapsed inward, replaced by a quiet, terrible clarity.

"So the twin surprise wasn't a celebration," Caleb said. "It was a staged collection event."

"She said we deserved it," Natalie sobbed, covering her face again. "She said Emma and Caleb had plenty of money, that Emma's family was rich, that Aunt Ruth had savings she wasn't using. She told me everybody does this now with digital registries and Venmo. She said nobody would miss a hundred dollars."

"You let her humiliate a ten-year-old child," Caleb said. His voice was steady, but there was a tremor of sheer rage underneath it that I had never heard in the entire time I had known him. "You let our mother look Sophie in the eye and tell her that three weeks of work wasn't good enough because it didn't come with a transaction fee."

"I was scared!" Natalie cried out. "Caleb, she was going to ruin my marriage!"

"You ruined your marriage, Natalie," Aaron said, his voice flat, hollow, and completely broken.

He took his wedding band off his finger. He didn't throw it. He set it down on the glass end table next to the sofa, right beside Natalie's prenatal vitamins.

"Pack your bags," Aaron said.

Natalie gasped, her eyes flying open. "Aaron, no! I'm seven months pregnant with twins!"

"Then you'd better go stay with the woman who bought them for you," Aaron said. "Because if you're not out of this house by five o'clock, I'm calling a locksmith, and your bags will be on the porch."
