This takes place during 3x11 (Michael). Thanks to ImaginetheWorldWicked (MEH not ALJ) for beta-ing this. I don't own Glee.
I walked into the bathroom and heard crying in one of the stalls.
"Hello?" I asked. "Who's there?"
"Nobody," I recognized Quinn's voice.
"Why are you crying?"
"Open up the door." I heard a clicking noise and the door opened.
"What do you want?" she asked.
"Why are you crying?"
"Because I feel bad for Blaine." she said, obviously lying.
"What really happened?"
"I saw Sam and Mercedes in the auditorium."
I went up to Sam and promptly slapped him.
"What the hell was that?"
"I just talked to Quinn. She saw you and Mercedes in the auditorium."
"Is she gonna tell Shane?" He asked, panicked.
"No. But I think I will."
"Why are you doing this to me Rachel? I though we were friends? I'm living at your house for crying out loud!"
"Because Quinn was in the bathroom crying her eyes out because of you. You are doing the EXACT same thing that you broke up with her for."
"Why does she care? She doesn't love me," he said. "Never has, never will," he mumbled.
"Excuse my language, but that's bullshit. She ALWAYS has. Do you remember how bad YOU felt when you found out Quinn cheated on you? That's how Shane's gonna feel if he finds out. Last year Quinn and Finn were doing the exact same thing you and Mercedes are doing. Remember how when Finn thought you and Quinn were together because of the motel you were ready to kill him? That's how Shane's gonna be except worse because he can beat you up and sit on you. Probably at the same time."
"I'll just ask Mercedes to break up with Shane."
"Okay, you do that. But remember Quinn and Finn don't end up together in the end." I walked away, leaving him with that to chew on.
"Mercedes, I love you. Please break up with Shane for me," I begged. She smiled at me. "Why are you smiling?"
"I came to the auditorium the other day so you would realize you love Quinn."
"I went to the auditorium to tell you we shouldn't be together, but you kissed me instead. I ran off because I felt bad for doing this to Shane and Quinn. If you love me then let me be with Shane and ask Quinn who Never Say Goodbye was about." She walked away. I saw Quinn a while later and ran up to her.
"Was Never Say Goodbye about me?" I asked her honestly. She looked down.
"I love you," I said to make her happy, but found myself actually meaning it. No way.
"No, you don't."
"Yes. I do. I realized I only forced myself to love Mercedes to get over you."
"I've always loved you."
"I could never say goodbye to you. And I'm never going to."
