"Anorexia?" Leonard cried.

"Yes." Gabriel said.

"What the hell?" Leonard exclaimed.

"Look. Leonard." Gabriel said. "Assuming from your reaction, I guess you never knew Mimi had anorexia."

"She what?" Leonard yelled.

"Mimi first developed anorexia when she was in 8th grade, before when I was adopted into her home. She was doing mathematics 18 hours a day, non-stop, and she thought eating was a waste of time when she could study. This worsened and turned into an eating disorder." Gabriel sighed. "I won't talk more about it. But I think the shock from her boyfriend's flight has triggered it back."

"What?" Leonard shouted.

"Quiet, Leonard, we're in a hospital." Gabriel said.

Leonard called Sheldon straight away. But he wouldn't answer. Leonard decided to spend the night at the hospital with Mimi.

"Leonard, I'm such a bad girl." Mimi said. "Who knows what could be happening to Sheldon? And all because of me? Oh, why didn't I tell Sheldon who Gabe was when we first saw him? I thought it would be better for everyone, especially Gabriel, but it was the worst choice I could have made!" Mimi sobbed, and Leonard could see Mimi's spine and the shoulder bones as she cried. She had always been thin, but not like this – the bones looked as if they were ready to pierce her skin any day.

Meanwhile, Sheldon was at the North Dakota police station. He was robbed. Again. He wanted to visit all the train stations in the country before returning home to accept Mimi's apology, but he guessed the journey had to end here.

Sheldon had the police officer dial Leonard's number. "Hello? Leonard?" Sheldon asked.

"Where are you?" Leonard yelled.

"I'm at the North Dakota Dickinson Police Department." Sheldon replied. "I was robbed. Please come pick me up."

"You stay right there." Leonard growled. The phone went dead, and Sheldon wondered what made Leonard so pissed off.

The next day, Leonard arrived at the police station.

"Oh Leonard, thank goodness you're here!" Sheldon said.

"Why did you have to run away?" Leonard cried.

Sheldon didn't say anything.

"Gabriel is Mimi's stepbrother!"

"Oh really?" Sheldon looked amused.

"Yes. And you're coming home this instance." Leonard snapped.

The day after, they reached Pasadena.

"Ah, home sweet home." Sheldon said. "As I was saying, Leonard, the train station in Denver used to have Heinz ketchup, but they apparently started using Del Monte, which I personally think is better." Sheldon looked out the window. "Hey, this isn't the way home!" He exclaimed. "Did you forgot to get new glasses prescribed again, Leonard? That's weird, you got new ones at the Moda Optique just last month."

"No, and no." Leonard said. "And FYI, I know."

"Then where are we going?" Sheldon asked.

"You need to see what you did to Mimi."
