Knock knock knock. "Mimi"

Knock knock knock. "Mimi"

Knock knock knock. "Mimi"

Mimi opened the door. "Hey, Shelly!" she said, cheerfully.

"Don't sing." Sheldon said.

"Excuse me?" Mimi asked.

"I said, don't sing." Sheldon said. "Don't go onstage next week."

"But why?" Mimi asked. "I thought you were happy for me."

"Just don't." Sheldon said, and went back to his apartment.

Mimi frowned. What was that about?

"Sheldon, come on, we have to go!" Leonard said. They were going to see Mimi's show tonight and Sheldon seemed to be trying very hard to be late! That was not like Sheldon – he was always early for everything.

"Remember what I said – if you don't want Mimi to leave you." Penny hissed.

"What?" Leonard said. He couldn't make out what his girlfriend had said to Sheldon. "Anyway, let's go!"

"I'm not going." Sheldon cried.

"Oh, for heaven's sake!" Leonard yelled, dragging him out of the apartment.

All during the show, Sheldon was having a troubled look on his face, and he even said no to snacks during intermission! That was odd, thought Leonard. Sheldon knew this was probably good for Mimi – and she did look as beautiful as ever. But thinking this would be the last time he would be seeing her broker his heart. Wait, wasn't he too evolved to feel those things?

No. He was probably so evolved that he could feel such feelings that would help his superior gene prosper… No. He knew he loved that girl dearly, and he wasn't going to deny it no more.

After the show was over, Sheldon and Leonard waited by the dressing room door for Mimi to come out. Even then, Sheldon was fidgeting and looking uncomfortable.

"Sheldon, what's the matter?" Leonard asked Sheldon, who was squirming.

"No, it's nothing." Sheldon said, gloomily.

"Come on!" Leonard said. "I know something's up."

"It's Mimi." Sheldon said. "She's getting fame, now she's going to get asked to sing in musicals around the world and she's going to leave me."

"What?" Leonard frowned. "Did Mimi tell you that?"

"No." Sheldon said. "Penny did."

Just then, Mimi came out from her dressing room. "Hey guys! How was the show tonight?"

And Sheldon just couldn't hold it no longer. He ran away from his friends. It was hard to face Mimi knowing he would never be able to see her again.
