Note: This completely unnecessary scene between Leonard and Mary takes place during 1.04, The Luminous Fish Effect.
Leonard brought Mrs. Cooper a cup of coffee. Sheldon was still pouting in his room, but Leonard was still glad he asked Sheldon’s mother out to help. Leonard was at a loss about the right way to help his best friend. Mrs. Cooper would know how to help. She had dealt with Sheldon’s craziness for nearly 30 years now.
“I’m glad you called me,” she told him.
“I’m sorry I couldn’t snap him out of it,” Leonard said.
“I’m an old pro at taking care of him. I can handle it. I’m more glad that you called because you care about him enough to make sure he’s taken care of. I wasn’t sure he would ever have that,” she explained.
“I don’t care about him that much,” Leonard said with an awkward throat clearing. He wasn’t sure what Mrs. Cooper thought his relationship with Sheldon was, but they weren’t dating. They were just friends. Well, best friends. Then he felt a little bit bad about saying he didn’t care. “I mean…”
“I understand, dear. I was thinking of when he was just a little boy. He had just started in high school at nine when he got a crush on a girl,” Mrs. Cooper started.
“Sheldon had a crush on a girl?” Leonard interrupted.
“As far as I know, it’s the only time, but yes. She was older. She could drive, and he was this tiny thing. Obviously it wasn’t going to work out, and he got his little heart broken. He swore up and down that he wasn’t going to make any more friends after that. Then he came out here, and he found y’all. It makes me so happy that he’s got you.”
“I’m still in shock that he had a crush on a girl,” Leonard muttered.
“What was her name? Linda? Lucy? It started with an L,” Mrs. Cooper asked.
“It was Libby, and I didn’t have a crush on her,” Sheldon shouted from his bedroom.
Mrs. Cooper smiled and winked at Leonard.
