As the summary says, set after s06e12 where the team investigates the ritual murders in Miami, Reid suffers from mysterious headaches and the team is still intact.
"What are you doing here?" Penelope asked in the corridor at BAU. "You must've landed a few minutes ago. Why don't you go to sleep?"
"It's an interesting case, I just wanted to find some more information about native religions and rituals," David said. "And the others, well, they've just decided to follow me," he threw his hands up.
"And what are you doing here, Baby Girl? Case is closed," Derek asked and slightly petted her cheek.
"Well, I thought that I might see y'all here," she winked. "I might've overheard you talking about the case on plane and that you want to find some more information about the case, yes I do have the equipment."
"Awww, so thoughtful," Derek cooed.
"Maybe I don't have to do the paperwork tonight," Derek whispered.
"I'm so tired too," Penelope added.
"I'm not here," Rossi announced to no one in particular and moved with JJ and Hotch to the bullpen.

Derek looked around and saw that everyone left, except for Reid who was awkwardly standing in the corner with his sunglasses still on.
"We could go to my place, Sweetness," he murmured.
"I'd love to see your home," Penelope replied and unobtrusively indicated to Morgan that he should watch Reid.
"I'd love to see your home," she repeated. "But the best thing would be for you to see me to my home. And I mean you both," she sing-songed.
"We both?" Derek wondered.
"I'm- am I having even … acoustic hallucinations?" Reid asked weakly. "I.. had some visual… ehm .. images," Reid tried to explain.
"Headaches," Derek mimicked to Penelope from where Reid couldn't see him.
"Ok, so my boys, one to the right, one to the left and we are going to my place," Penelope decided.
"Sit tight, I have something what you need," Penelope told them when they entered her apartment.
"We need something? I think I got all the documents," Reid answered confused, still thinking about the case.
Penelope took three mugs out the cupboard and said to herself: "Maybe a double dose…"
Reid immediately put his hand over one of the mugs. "I can't. This much alcohol, this wouldn't end up well."
Derek laughed.
"You'll get hot chocolate."
"We've been in a desert, not a desert, but in desert-like weather for the last few days, Baby Girl, have some mercy," Derek protested.
"Love has no mercy," Penelope announced and made them delicious hot chocolate.

Derek put a light kiss on Penelope's hand when she was serving them the beverage.
"Ehm… I could … maybe go home or … return later … I," Reid mumbled into his mug.
"Or you can go and lie down in my bed and rest for a while, you do look like you need it. And after you rest we can have some fun," she said and didn't explain further.

Reid took off his red jumper and tie. Derek put an arm around his shoulders. "The bed looks comfy."
Reid smiled shyly at him.
"Maybe it's not a bad idea," he conceded and let Morgan help him into the bed and cover him with a blanket.
"And what do we do now? Your home your castle," Derek asked.
"We'll make us comfortable and talk," Penelope whispered.
"So the first question is… Is this all real, Baby Girl? How have we ended up here? I've been gently flirting with you for months, years even…"
"Exactly," she exclaimed.

"Well, what?" Penelope turned to Derek and then to sleeping Reid. "I do wear these fancy glasses but I'm not blind. Reid's been looking at you. I mean looking at you," she repeated in a seductive voice. "You've been looking at me. And nothing! You can't be calling me Hot Stuff forever without making a move."
Derek started to protest but she quickly covered his mouth.
"Shhh, and because I'm a woman with a big heart and sometimes indecisive and because we are almost like a family…"
"You've invited us both," Derek finished the sentence for her and put a kiss on Penelope's forehead.

"He also deserves some love," she pointed to Reid in bed.
"Right now he deserves some sleep."
"Sleeping and cuddling are not mutually exclusive," Penelope winked.
"I can hear you," Reid whispered sleepily.
"And? Any objections?" she asked.
"I don't know your exact definition of cuddling. I do know that Cambridge dictionary specifically talk about two people: 'to hold each other close to show love or for comfort'." Reid sat up and began enumerating the definitions.
"Though the Merriman-Webster dictionary classifies it as a transitive verb and doesn't specify the object, like "to hold close for warmth" without saying whom. It even gives an example with a dog. And then of course it's also described as an intransitive verb with the meaning of lie close."
"Now you talk some sense," Derek quipped.
"Lie down, Pretty Boy. And we'll lie close," he smirked at Penelope.
"I think I can do that," Reid said, relaxed his muscles and leaned on the big pillow.

Penelope returned in a nightdress. "No feathers? No rhinestones?" Derek asked, supressing a grin.
"Cotton, my dear. You don't know this videogame so don't laugh, but this red one here is Seiko and this one is my guy Hoshi, I programmed them."
"Ok, for a minute I felt out of my comfort zone but everything is back on track with Reid citing dictionaries and you developing video game characters and printing them on your nightdress," Derek noted and finally took off his jacket and jeans.
Penelope's bed was indeed big. She climbed on the left side, Reid was sleeping in the middle and Derek sat down on the right side.
Reid wiggled in his sleep and unconsciously put his hand on Derek and pulled him down.
"Someone is impatient," Penelope giggled.

Derek stretched in the bed. "It is indeed so comfy here. I'm so glad you've made us come here."
"I do have good ideas, sometimes. And my other good idea is-," Penelopa said and leaned over Reid to Derek. "-that I will kis-"
Derek also propped himself on his elbow, leaning over Reid forward towards Penelope anticipating the kiss.
In the moment when they almost touched with their lips, Reid woke up and immediately proceeded to sat upright because probably something had crossed his mind and he needed to write it down.
Apart from various little knocks and tumbles between all three of them, Reid's head got caught in the middle, resulting in Penelope and Derek kissing his cheeks.
