Here's a short story that I got the idea for after rewatching some of my old favorite season 9 carby episodes.
Giggling could be heard from down the hallway. John Carter walked faster to the drug lockup. He recognized those giggles.
"And then what did he do?" Carter heard Susan ask Abby as he hid behind the corner.
"He told me he wanted to marry me! Except he screamed it, because a helicopter was coming, and I told him he was crazy."
Carter's smile disappeared. He was getting pretty pissed. This was their private business, and Abby was telling Susan like it was an everyday matter.
Listening closely, John heard Susan gasp in surprise. "Oh my god Abby, you're getting married!" she cried, and proceeded to hug Abby so hard that she almost suffocated.
"Well I didn't say 'Yes' to him," Abby told her friend in a condescending tone.
Carter, who was still standing right around the corner from them, felt like he had been smashed on the head with a baseball bat.
Blinking back tears, he ran as fast as he could away from them, knocking over a cart full of medical supplies on his way.
Carter barreled into the men's room. He was lucky, there was no one else in there. He leaned his head against the wall and took a deep breath. He tried to calm himself down, to no avail.
Meanwhile, Abby was looking everywhere for her boyfriend. She wondered how much of their conversation he had actually heard, and if he was hurt or not. All she had seen was his retreating back as he flew around the corner.
"Frank!" Abby yelled across the room. "Where's Carter?"
"Do I look like his keeper?" Frank asked.
"WHERE THE HELL IS HE?" Abby screamed, any trace of politeness was gone from her voice.
"He just went into the bathroom, I think," Frank told her. He took another bite of his donut and went along with his work.
Abby, however, took off at a sprint towards the men's bathroom. She knew how sensitive Carter was, and she wanted to get to him fast.
Panting, Abby pushed open the door to the restroom and saw John Carter wearing the most miserable look she had seen in her life.
"Hey," she said softly, walking up to him and placing a hand on his arm.
Carter cringed at her touch and backed away.
"What did you hear?" Abby asked him, looking straight into his eyes. "Did you bother to listen to the rest of the conversation? The part where I told Susan that the day I married you would be the best day of my life?"
John turned sharply when he heard this last part. "What?"
"John, look at me," Abby said. He loved it when she called him John. "I love you. I want to grow old with you. I want to have babies with you, and I want to wake up next to you every day for the rest of my life. Will you marry me?"
Carter smiled and wiped his nose. "I asked first," he said with a grin, and he leaned in for a kiss. It was the most amazing kiss they had ever shared, because he finally knew that it was forever.
Well there it is. I'm still debating whether or not I should leave it like this or turn it into a story. Whatever you guys think!
