As Grace boarded a flight home from visiting her mother, she never expected to sit beside her husband’s ex-wife.

What began as an awkward coincidence quickly turned into something more unsettling. Clara, calm and curious, recognized Grace and casually began talking. She mentioned recent contact with Oscar — texts, calls, and a dinner “to catch up.”

Grace sat frozen, unsure whether Clara was being friendly or subtly warning her.

Now, the plane has landed, and Grace is sitting alone in the airport coffee shop. Clara’s words echo in her head.

Was Oscar hiding something? Or was Clara stirring the pot for her own reasons?

One chance seat assignment has left Grace questioning her marriage — and wondering what she’ll say when she walks through the front door.
