We never do learn if Tony ever found out about what happened to Nkki's brother after he got out or Iraq but assume he did. Also, assume that American University has online classes because I don't know if they do for real.

"Hey, Jimmy, what do you know about comas?" asks Tony from behind his laptop screen where he is merrily typing away.

Jimmy raises an eyebrow. "I thought that you were writing an essay about the use of film as a propaganda tool, not an essay about comas," he remarks.

Tony just rolls his eyes. "Not the point, Palmer."

Jimmy looks up from the book about gross anatomy to find that Tony is looking at him expectantly. They are once again in the George Washington University library; it had become a weekly ritual for them to meet up in one of the libraries and to study together. Jimmy surrounded by his medical textbooks and Tony with his books on film or with his laptop writing another essay. Ever since his time with Jeanne Tony found that he actually liked taking the film classes and had been in talks with the dean of the school and director of the program wanting to know if it was possible for him to be in, assuming he gets accepted of course, the Master's program with a job as unpredictable as his. It had been decided that they could accommodate his schedule now that they recently added many of their Master's level courses to their ever growing on-line class option so they encouraged him to apply. Tony had applied and was accepted and after working out the days that he'd have to leave early with Gibbs the Director became a part-time graduate student at American University.

"Well, it depends, what do you want to know about them?"

"Um, everything?"

"Well, then I guess we should start with the causes for comas, for example: traumatic brain injuries, lack of oxygen, diabetes, stroke, toxins and infections are just examples of some of the causes."

"What about the chances of coming out of one?"

Jimmy frowned, unsure of how to answer that question. There were so many variables involved that it was almost impossible to say how long someone would be in a coma for, what kind of, if any, permanent damage was sustained or even if they would ever come out of the coma.

"That depends."

"On what?"

"Many things, the cause of the coma and the duration are two major things though. We haven't covered neurology in-depth yet, Tony," he said apologetically.

"It's okay, Jimmy."

"Does your sudden interest in neurology and comas have anything to do with Nikki?"

"Not my story to tell, Palmer."

"Okay but if you want, I can direct you to some books and journal articles that might be helpful."

"That'd be great, thanks, Palmer."
