I pressed my forehead against the cool window. Closing my eyes, I took in a deep breath but the tension didn't fade. It felt like there was a rock on my chest. Voices around me felt muted. The entire world seemed to have lost its colour. 

I replayed the events of this morning in my head. Visiting Kat, seeing Zane by her side, Kat placing Zane's hand in mine. Then there was me, pulling away and trying to make sense of her strange proposition. 

I didn't know Zane. He didn't know me. We were strangers but there was one person who united us, a person who we would be willing to do anything for. 

"We don't have to do this," a voice said behind me. His head was hung low and he appeared hollowed out. "She's really sick and...and the drugs are making her say things."

Kat was like a mother to me. It was hard to walk away from her final wish. Before getting sick, she constantly talked about walking me down the aisle. When she wasn't talking about my wedding, she would always talk about her son's marriage. 

"This is her last wish." Even as I said those words my stomach twisted in pain. "We can do this for Kat."

"For Kat," he responded.

That night, I married a stranger in a dreary-looking hospital room. My dress was white but simple, a quick purchase from a nearby thrift store. Zane bought a bouquet of roses from the gift shop downstairs and mumbled an apology to me as he handed them over.

Kat passed away nearly a week after Zane and I exchanged hastily-written vows. The one thing that kept us going was Kat's smile and tears of joy when Zane slipped a ring onto my finger.
