The agents of the BAU were departing for Honolulu, Hawaii, where a large number of murderous with similar MOs had occurred, and they were concerned because it was really the first incident of a serial killer in Hawaii ever. The thing that most worried Dr. Spencer Reid was that all the victims were Japanese and didn't speak English, and neither did anyone in their immediate families. He wondered what the deal was, but the FBI was providing them with an interpreter from the Honolulu field branch so he figured that would alleviate any language barriers or problems arising from that.

The team, including Garcia, chatted about things including the case and wondering who their interpreter would be. Then Garcia got the magical idea to look up case files by hacking into the Honolulu Field Office's employment data and finding all the Japanese language interpreters on their payroll; there were four of them, and one of them specialized in Japanese, Korean, and Chinese, but was also adept at Spanish. Her name was Aida Ivanova-Ishikawa, and she instantly attracted the attention of JJ, Morgan, Rossi, and even Reid.

"She's most likely who we're working with, given her extensive background in the three major Asian languages; it says she speaks both major types of Chinese… And she really likes techy-stuff." Garcia smiled a little. "I bet we'll get along."

"I-I think I know this woman." Reid looked surprised when he got to see her photo. "I mean, her hair is a lot longer and it's not the same color and she's a little tanner than before, but I think I know her!"

"What?"

"I'm assuming she's married, due to the hyphen in her name, but I knew a woman named Aida once, and she was a good friend of mine; well, until she decided to throw me under the bus with regards to our relationship." He sighed. "She's an ex-girlfriend of mine." He muttered. "That's definitely her; that look in her eyes is the same as when she left me." He was now really wanting to jump into the cockpit and turn the plane around and head right back to Quantico, but he couldn't do that without getting in trouble for it.

"What?" JJ looked surprised. "You had a girlfriend before Maeve?" She asked.

"Yes… Never went on a date, but we were together for almost three years…" He muttered.

"Maybe you can rekindle some old flames!" Garcia said hopefully.

"No, I don't think so." He suddenly looked depressed. "She made it clear it was over." After that, no one said anything and they let Reid sit in his seat in silence for the rest of the plane ride.

When they touched down in Honolulu, they were escorted to the FBI field office and were given an introduction to all the agents working on the case at that moment. Much to Spencer's relief, Aida wasn't in the building at that moment, and he could work in peace for a few hours before she was supposed to come back. Like clockwork, three hours later Aida came into the building. As soon as she spotted Spencer, though, she bolted into her office.

"Sheesh, kid; what happened?" Morgan asked, sitting down with Reid in the office he had been given to work in.

"I-I don't think it's got any relevance to the case, so can we just not talk about her?"

"Reid, obviously something happened between you two and it's bothering both of you."

"Derek, please don't ask me about it again." Reid snapped. "Sorry, but I really don't want to talk about it." He sighed frustratedly and tossed his pencil onto the table.

"Alright, fine; but you know you're going to need to talk about it eventually." Morgan got up and walked away. He then walked over to JJ. "He's going to blow a gasket soon, I know it." He said.

"She looks pretty upset too, but more depressed than he is; he just seems angry and resentful." She replied, sighing. "I wonder what happened."

"So do I, but I have a feeling it's going to get in the way of our job if this keeps going on."

"Conference room. Now." Hotch demanded as he walked past. "Get Mrs. Ishikawa as well." He marched off and both the agents looked confused. Morgan let Reid know they were meeting in the conference room, and JJ got Aida to come with. The worst part was that there were only enough seats to accommodate their team and Aida, and Spencer was stuck having to sit next to her.

The whole time, both Spencer and Aida threw out theories about the unsub and continued to argue back and forth about how the other's theory was complete crap. It reached a peak when Spencer decided to pull something no one would have expected from him.

"You're not a profiler, I am. You didn't get the spot in Quantico so you're hardly fit to make profile calls, Aida." She looked angry with him but said nothing while he continued. "Stop trying to be what you obviously aren't." She sighed as though resigning herself to Spencer's verbal dis of her; she seemed to have been expecting it.

"Yeah, you're right." She sighed; both of them knew that both of their theories were all entirely plausible and most likely correct, but there was just so much resentment on Spencer's side and so much guilt on her side that they just went about things in the fashion they had just displayed. "Sorry, I'll just keep my mouth shut about anything other than what you need me to interpret or translate…" She looked away from Spencer. "Sorry, Spence…" She muttered.

He looked like he felt absolutely no remorse for being so rude to her, and JJ figured she probably must have done something really bad to him to make him be like that with her, because everyone knew Reid was a real sweetheart unless you pissed him off.
