The next morning, Leonard woke up and discovered that Sheldon was not in the apartment. That was odd. A walk in the morning was not a part of his daily schedule.
It was when Leonard went to the kitchen to have some breakfast that he saw the note from Sheldon. It read, 'I'm running away until things get back to normal. Call me when it does.'
Leonard phoned Sheldon.
"Hello? Leonard?" Sheldon said from across the telephone.
"Where are you?" Leonard shouted.
"Nowhere." Sheldon said. "Why did you call me? Did you see my note? Are things back to normal yet?"
"I don't think so." Leonard said.
"Then why did you call me?" Sheldon asked.
"Sheldon, this is insane." Leonard said. "Why did you run away in the first place? Because Mimi is busy with Gabriel?"
Sheldon didn't answer.
"Good day Leonard." Sheldon said. "Call me back when things get back to normal." And he hung up.
Leonard groaned. So that was it! Sheldon was jealous of Gabriel! But who was Gabriel anyway?
Leonard grabbed his coat and left the house, and drove as fast as he could to the hospital. He went straight to Mimi and said, "Mimi, Sheldon ran away from home."
Mimi looked surprised. "Ran away from home? Why?"
"I think he was jealous about you fussing over… you know, him." Leonard gestured toward Gabriel.
"Gabriel? Why?" Mimi asked.
"I don't know." Leonard said. "Perhaps he thought he had to compete with him to win you back."
"What are you talking about?" Mimi said. "Gabe is my stepbrother!"
"What?" Leonard said.
"Yeah. We've been friends until his parents… you know. Passed away." Mimi lowered her voice. "My parents adopted him because they were such good friends with his parents as well, and he became my stepbrother. I've always had a soft spot about him." Mimi sighed. "I can't believe Sheldon thought of it that way!"
"Well, you'd better call Sheldon." Leonard said. And Mimi did. But Sheldon didn't answer. She called him at least a few dozen times, but he didn't answer to a single one.
"Oh my gosh." Mimi said. "I don't know what I did."
"Mimi, it'll be ok." Gabriel said.
"No, Gabe, you don't understand." Mimi cried.
"Don't I? Then what about that time with Giana?" Gabriel said.
"Fine, I'm sorry." Mimi said. "But Sheldon – he's different. I guess I made him very upset. Oh, what have I done?" Mimi broke down crying.
"Mimi, I am so sorry." Leonard said.
"No, it was my fault." Mimi sobbed.
For the next few days, Leonard stayed with Mimi and Gabriel at the hospital. Both Mimi and Leonard called Sheldon plenty of times, but Sheldon seemed disinterested. Mimi never stopped crying. Nor did she eat anything. And then one day, Mimi fell unconscious while crying.
Leonard thought she'd ought to wake up soon, but when she didn't, Gabriel called the doctor and she was put into bed. She was given glucose injection, and when she woke up, Mimi was diagnosed anorexia nervosa.
