Chapter 15:

"So you guys all knew about this?" Abby asks everyone at admit a while later, still smiling. She still can't believe how clueless she was this morning.

"Yeah, took us a while to catch on, but eventually we did. Just can't believe you didn't!" Sam says jokingly.

Things were going slow in the ER at the moment, so Abby asks Sam if she still wants to go get coffee and talk about whatever. Sam agrees and they walk over to Doc Magoo's.

"So today was an eventful day," Sam says, sitting down at a table in the diner across the street from the ER.

"Yeah," Abby says smiling, "The only thing that worries me is Kem," Abby says, her smile fading away.

"Why do you think she is gonna come back or something?" asks Sam.

"No, it's just… do you know why they broke up?"

"No."

"That's exactly it. He won't tell anybody, not even me. And I know its something big. He almost gave up his life here to go be with her, and then all of a sudden he's back. Something big happened Sam, I just know it."

"Why don't you just ask him about it?"

"I have, and he gets all upset."

A few minutes pass by without the two of them saying anything. Then, all of a sudden Sam realizes something. "Luka knows," she tells Abby.

"What?"

"I think Luka knows why they broke up."

"What? How?"

"Before Carter came back, Luka got a separate letter from him. It was mailed to our place not the ER. It was a long letter, and for some odd reason Luka didn't let me read it. I didn't think much of it then, but now that I'm thinking about it, the letter must have contained something John didn't want anyone else to know. Something about why he was coming back."

Abby stares at Sam, her mouth wide open. "We have to get that letter," she says.

"I know," Sam replies. Even though she knows that she shouldn't look at that letter, she knows she has to find it. It was the only way to help Abby, and Abby was her best friend. Luka might get angry, and well Carter would to, but she had to find that letter. It was the only way to help Abby and Carter.
