My sister, Nadia, is a year younger than me. Growing up, some kids avoided her, or treated her like she was somehow less than the rest of us, because she has Down syndrome.
But not my best friend, Marcus.
“Nadia, you’ll always have me and Marcus,” I used to tell her, back when we were kids and that promise felt like it could fix almost anything.
⸻
Marcus was always there for her. He made sure she was never left out of a single birthday party, a single school trip, a single ordinary afternoon the rest of us took for granted. In fourth grade, he told her, completely seriously, that one day he’d take her to prom himself.
He kept that promise seven years later, showing up at our door in a rented tux, a corsage that matched her dress exactly, treating that entire night like it was the most important date either of them had ever had.
⸻
For years, everyone around us assumed Marcus and I would eventually end up together. Best friends since kindergarten, inseparable through every version of growing up. Instead, once we were older, he asked Nadia to marry him.
I cried harder than she did when she told me. My best friend had somehow become my brother, and my sister had found a kind of happiness I don’t think either of us fully expected life to hand her.
⸻
When Nadia announced at their wedding reception that she was pregnant with twins, the entire room erupted. Our parents cried. I cried again, the good kind, watching my sister glow through an announcement she’d clearly been saving all evening.
But the pregnancy turned difficult almost immediately.
⸻
Nadia has a congenital heart condition, something she’s had since birth, common enough among people with Down syndrome that our parents had explained it to me matter-of-factly when we were young — a small hole in her heart, repaired surgically when she was still a baby, monitored closely every year since, but stable enough that it rarely came up in conversation anymore by the time we were adults.
I understood it as background information, something true about my sister the same way her favorite color was purple and she couldn’t stand cilantro. I didn’t understand, until much later, exactly how much weight that condition still carried.
⸻
At thirty-four weeks, Nadia was rushed to the hospital, her blood pressure spiking dangerously, her heart showing signs of strain the doctors described to us in a small consultation room with a seriousness that made my own chest go tight.
They were doing everything they could, they told us, for her and for both babies. They gave us very little reason to feel hopeful in that first hour.
⸻
Marcus never left her side, not for a single minute, until the surgical team finally made him step out while they prepared her. He looked completely drained of color by then, terrified in a way I’d genuinely never seen on him in twenty-three years of friendship.
Then, out of nowhere, he grabbed my hand and pulled me into an empty side hallway, away from our parents, away from the noise of the waiting room.
