The Glee club split up years ago. It all fizzled out after everything hit the fan. First Will found out Terri had been lying to him. He had went to Emma for comfort and they had slept together. Then Will had left town. No one really wanted to take over Glee so it ended. But the Glee club members didn't go back to routine. Though most of them did stop talking.
Quinn broke it off with Finn to date Puck. Though she never told that the baby was not his. Finn tried it out with first Rachel then tried to get back with Quinn. When that fizzled out he hooked up with Kurt. Over the past four years it has been on and off with all three of them. Puck broke up with Quinn when he realized he couldn't stand her. Later he ended up married to Mercedes. Tina married Artie.
Nine months after Will left Emma had a beautiful little girl. But never contacted Will. She didn't have the heart to. And this is where our story begins. Ten years after they all moved on. And two girls quest for the truth about themselves.
