"I see the way you look at him!"
Cho's voice is raised and strained, almost hoarse from crying.
"And I see the way he looks at you!"
Despite being by the lake in a time when most are readying for bed, Cedric can't help but look around, nervously, hoping no one is around to hear them.
"You used to look that way at me!" Cho points out, between gasps of tears.
Cedric steps to close the distance between them. Cho lets him for a moment, taking small comfort that he is here with her; at least, for right now. Her resolve quickly returns. She takes a step back, holding up her hand in an effort to keep Cedric at bay and show him that he is unwanted.
It works.
"Cho," Cedric says, "I didn't mean for any of this to happen."
He doesn't know if there's any honesty in those words. He knew she could never be for him what he was for her.
Cho almost believes him; he can see it in her eyes. They beg for him to take it all back, beg for someone to wake her to reveal that it was all a nasty dream, beg to be loved as selflessly as she had love in return.
"How long?"
Cedric is bemused, not by the question, rather by the accusatory tone of her voice: icy and disconnected, It gives Draco Malfoy a run for his money.
"Wh... what?" is all he can muster.
"How long have you been fucking him?" she asks, slowly with a sneer.
"Cho don't be so crass."
He turns to face the Great Lake, reflecting the moonlight in iridescent waves; shifting as the water rises and falls as if dancing to some great song that Cedric is not allowed to hear.
Cho grabs his arm, forcing him to look at her. Cedric is surprised at her vice-like grip.
"Answer me," she demands, her voice no longer trembling.
But Cedric can't answer.
"What does he have?" she asks, "What does he have that I don't? What can he give you," she continues, clutching at her chest, "that I can't?"
Cedric bows his head.
"It's not about what you are," he says in a calm whisper, "It's about what you're not."
He snaps up, looking, for the first time, directly in her eyes.
Cho is startled by the truth they reveal; by its brutal honesty and its final resolution.
"You're not him."
The moment seems to last forever.
As Cedric turns to walk back into Hogwarts, he begins to understand.
This must be what it sounds like when you break someone's heart.
