A/N- This one is Reid! It was a lot of fun to write, and hopefully it will be just as fun for you to read!

Emily got poison ivy when she went trekking through the woods with Rossi as the team investigated the suicides at the military school. Garcia was quick on the alcohol swabs, and Emily only ended up getting a small rash.

Reid watched from his seat across the aisle from the jet as Emily scratched at her arm.
"You shouldn't scratch the poison ivy." He advised, "If you break the blisters, they could end up scarring over."

"I wasn't scratching." She weakly protested, pulling her sleeves back down over the red skin.

Reid merely shook his head and went back to reading his current book. The cabin lights dimmed as many agents nodded off for the flight back, Reid flicked on his overhead to see his book clearly. Reid finished his book, and stood to find himself a cup of tea, and when he returned, he caught a sight that brought a smile to his face.

JJ was holding Prentiss's hand in her own, running her free one up and down the brunette's arm to provide some light relief for the burning rash. It was nice for him to see how well the two women got along. He had always looked at JJ as a sort of a mother figure, and Prentiss as an older sister, the team was his second family, and it was moments like this that made him feel that unconditional love.

…

Exactly two days later. after the team had arrived back from the case, they was sitting in the briefing room while JJ stood in front of them going over their newest case. Her sleeve slid up her arm slightly, and Reid identified the redness he saw there easily.

As the blonde continued on in her briefing, he couldn't help but interject, "You have poison ivy."

"No, I don't." JJ replied immediately, subconsciously pushing her sleeve back into place.

"Yes, you do." His eyes narrowed, "Where did you get it?"

JJ sighed as she gave up trying to lie, "I don't know Reid, a poison ivy bush?"

He accepts it for a full five seconds before something else occured to him, "When? There's been literally no time for you to have gone into a wooded area and come in contact with the plant. Not to mention, it's not indigenous to the area. You would have to have driven nearly four hours to encounter a plant in the wild."

Morgan smirked from across the table, "Prentiss, didn't you have poison ivy just two days ago?"

Reid shook his head, "Poison ivy is only caused by direct contact with urushiol oil. JJ couldn't have gotten the rash from Prentiss unless she was in direct contact with the clothes that Emily was wearing when she walked into the woods."

JJ ignored the both of them, continuing on in her briefing. Morgan's smirk grew while Reid was simply puzzled. He tried to reason out the poison ivy connection, but was drawing a blank.

…

Reid, Prentiss, and JJ were all gathered around Garcia whose fingers were flying across her keyboard at lightning speed.

"I cannot believe this is happening." Prentiss said from over Penelope's shoulder.

"You had better believe it, big eyes." In moments, the screen was filled with the image of Hotch, but not Hotch as any of the team knew him. Rather, it was a photo of Hotch in high school. He was in the awkward phase just after his freshman year where his body was nearly fully grown, but he still didn't know how to operate it quite yet.

His shoulders hunched slightly, and his too large ears stood out goofily from his chiseled chin.

"This is too good." Emily laughed, her eyes scanning quickly over the photograph.

"Do Rossi next!" JJ suggested excitedly.

"Your wish is my command." Garcia said, already typing.

While the tech genius was working her magic at the computer, Prentiss backed up just the slightest, and searched behind her for a mug. She brought the ceramic to her lips triumphantly and sipped at the lukewarm coffee. It was sweeter than she was used to, and almost immediately, Emily knew her mistake, though she tried to play it off like it was nothing and she took another long sip.

That done, she set the mug down on the desk, "Not next to my baby!" Gracia immediately chastised.

The brunette rolled her eyes, but complied, picking up the mug.

"What shade of lipstick are you wearing, Emily?"

"What?"

Reid pointed at the lipstick stains around the rim of the mug, "What is the shade called? It doesn't hardly show up on your lips."

JJ smirked, "Yeah Em, what color do you wear?"

Prentiss's eyes narrowed on the blonde, "It's something new I picked up a few months ago." Emily replied, her tone laced with double meaning. JJ's rose her eyebrow in challenge, the two of them had just started dating a few months prior, "I thought it was a good match, but I'm starting to have my doubts."

Reid was lost as he looked from the rim of the mug to Emily's mouth, the shades didn't quite match, but he just chalked it up to most of it having rubbed off over their long day of work.

…

For all his education and all his raw knowledge, poor Reid never did catch on until the relationship was put right in his face in a way he understood. He became suspicious truly when the team was flying all the way out to California for a case. On the way out, he played his usual game of chess with Rossi. After losing terribly, to the older man, Reid took a moment to stare intently at the chess board. He played the game over and over in his mind, pinpointing the moves that had lead to Rossi's victory.

He was jolted from his studying of the board when a dark haired agent slid into the seat opposite him that Rossi had just vacated.

Without saying anything, Prentiss began resetting the board. When it was back as it should be, Emily smiled, "White moves first."

Reid returned the smile and they began to play.

They had done this multiple times before, and even though he had seen Emily's signature moves dozens of times flying across the country, he couldn't beat her, and she got to checkmate in fifteen moves.

With a victorious grin, Emily made her way back to the rear of the jet where she sat with JJ. Their heads close together in conversation.

The case went surprisingly well, the team managing to catch the unsub before he killed any more victims. Before they knew it, they were back on the jet headed to DC.

Moment after the jet was airborne, JJ was practically bouncing down the aisle to sit across from Spencer. He put his book down, regarding her with interest, "You, me, chess, now."

Reid fished the game out from where they stored it beneath the table and began setting up. This wasn't the first time he had played JJ, but it was the first time that she initiated the game. Normally it was him begging and pleading until she relented, unlike the other members of the team, she had never played growing up, and she was simply less experienced.

Now Reid watched with interest as JJ relied heavily on her knights to take out several of his pieces. Her style was crude, yet effective, and once she had the opportunity to corner his king, Reid's eyes practically bugged out of his head.

"Prentiss!" He exclaimed loudly, nearly jumping out of his seat in the realization.

"What?" JJ asked innocently.

"You and Prentiss, she and you!"

"Reid, I have no idea what you're talking about"

"That's her move!" He said, gesturing at the chess board, "She must have taught you, but you hate chess."

JJ merely shrugged, smirking lightly. She left, resuming her normal seat with Emily.

When Emily greeted the blonde with a soft smile, and JJ rested her hand on Emily's thigh, the two snuggling together for the remainder of the flight home, everything finally clicked for him.

"Check mate." He whispered under his breath, shaking his head, his cheeks flushing slightly under his realization.
