This chapter is brought to you by my aversion to homework and my 4th time rewatching criminal minds:

Spencer groaned as he learned he would not be able to spend Halloween in DC. Instead the team was needed in Detroit.

You smiled as you saw your phone flash. "Spencer, I missed you," you said excitedly. You heard him laugh.

"I miss you too. I'm also really sad that you have to cancel your trip on Friday," he said softly. You frowned, your heart hurting at the thought of not seeing him.

"A Case? Where this time?" you asked, taking a sip of your coffee.

"We leave for Detroit in the morning. Something about Devil's Night."

"I'm sorry Spence, I know Halloween's your favorite," you consoled.

"I know, I was going to take you to the Edgar Allen Poe shadow puppet theater. Or maybe the reenactment of the 19th century phantasmagoria," he said excitedly, making your heart flutter.

"Aren't phantasmagorias the ghost shows from France?" You asked, twirling a pencil between your fingers.

"Yeah! They use science magic," he said happily. You frowned, realizing how excited he had been for this weekend, especially to show you his favorite things.

"I will admit I would've loved to see some science magic. But, it's not a big deal. Besides, what's another two weeks in the grand scheme of things when we've gone this long?" You continued.

"I don't deserve you Y/N, not one bit," he muttered. "I love you and I'll see you soon."

"I love you, bye." You heard the phone click and held it over your heart. You were really looking forward to seeing him. It seemed the universe had other plans.

The following day, after 12 hours of trying to put together a profile, Spencer decided to head to the hotel to try to get some sleep. He rubbed his eyes as he walked into his room. Somehow, Garcia had managed to get everyone single rooms. But, Spencer's was on a different floor.

He looked up and his eyes shot wide open. You were laying in the bed in a skimpy set of black lingerie and a black cat ears headband. "Trick or treat," you teased, causing him to cough.

"Oh it's most definitely a treat," he said, walking up to you and capturing your lips. You grinned and wrapped your arms around his neck, pulling on his hair.

"I like this haircut Dr. Reid," you whispered.

He growled softly, latching his lips onto your neck. "You look so good," he said hungrily, his lips touching every part of you.

"Well, everyone deserves something sweet on Halloween," you said softly, picking up the chocolate fudge from the nightstand and smearing it along your neck. Spencer took a breath, swallowing heavily before licking the chocolate. You grinned and smeared some more on your chest, a bit lower this time. He licked it up quickly.

You did the same, this time moving your top to the side. Spencer grinned and wrapped his mouth around your tender tissue, sucking softly. You moaned quietly, throwing your head back. He looked up and pouted. "Is that all the sugar im getting?" He asked in a low voice. You squeezed your legs together, trying not to show him the control he had over you.

"If you want more, all you have to do is ask," you spoke, smearing more fudge along your abdomen, straight down until it hit the the lace of your underwear. Spencer licked it up quickly, reaching the hem of your underwear. He used his teeth and lowered them, dipping his head into the space between your legs.

"God, Y/N, you taste so good, even better than the fudge," he muttered, looking up at you, your eyes half-closed and your head thrown back as he brought you to the edge. He smiled and moved up, kissing you gently. "How did I get so lucky?"

-

You were relaxed in Spencer's arms, his fingers tracing patterns in your shoulder. "In case I haven't said this enough, I'm in love with you," he whispered, kissing your neck. You smiled and snuggled further into his arms. "Not that I'm complaining, but how did you manage all of this?" he continued, peppering your shoulder with kisses.

You smiled, looking up at him lovingly. "I felt bad because you were going to miss out on your favorite holiday. So I called Garcia to ask what hotel you were staying at so I could send some candy and a few movies for you. But, she had the brilliant idea to transfer my plane ticket to DC into one from Boston to Detroit. So, I flew out this morning, taking a 'sick day' from work in order to surprise you."

Spencer grinned. "I don't deserve you."

"Hush, you are brilliant and handsome and funny and sweet and seriously perfect. I love you and no one else Spence. Never anyone else. Please stop pretending like you aren't one of the most important people in my life."

He smiled, kissing you softly. You tangled yourself into him further, leaving no space between your bodies. He groaned, his hands roaming your bare skin. "I want to marry you one day," he muttered, kissing your neck. You froze, blinking rapidly.

Did he just say those words out loud? You looked at him, his arms wrapped around your waist, his head buried in your neck. He didn't look surprised by the words. You shrugged it off. He must've been caught up in the moment. There was no way he thought that. You had only been together a little over a year, it was insane to consider that. Right? He'd said variations of it before, but never outright.

"Y/N?" Spencer called, bringing you out of your head.

"Hmm?" You hummed in response, smiling at him.

"I said, 'we should shower pretty girl." You nodded, getting up. Spencer followed, wrapping his arms around your waist. "I love you," he whispered, kissing your cheek. You smiled, butterflies in your stomach. It was crazy the effect he had on you still. He stepped into the shower, pulling you in after him.

"I love you Spence," you whispered as you stepped out of the shower, wrapping yourself in a towel.

"Y/n?" He asked. You turned and looked at him, smiling slightly as you watched the water drip down his body. "Did you hear me earlier?"

You took a breath and looked at him in confusion. He couldn't be referencing what he had said. There was no way. "What did you say?" You asked, leaning against the sink. He took a step towards you, placing his hands on both side of you.

"I said, 'I want to marry you one day," he whispered, his lips inches from yours. Your breath hitched in your throat, making you pause.

"Spence," you muttered. "I-" you began before you heard a loud knock on the door. Spencer sighed and stepped away, walking to the door and opening it.

"Hey man, sorry to bother you, but we have a lead. Hotch wants us at the station in 20 minutes," you heard Derek say. Spencer nodded and closed the door, walking to his bag. You frowned and walked behind him, wrapping your arms around his torso.

"Spence?" You whispered, to which he said nothing. You groaned and pulled his towel gently. "Spencer Reid, look at me," you ordered.

He turned and met your eyes, his slightly red.** You cupped his face end kissed him sweetly. "I love you and I'm yours, for however long you want me," you said reassuringly. He looked at you lovingly, wrapping you in a tight hug.

"I meant forever," He whispered, his arms holding you firmly. You pulled away slightly and looked at his beautiful face.

"Now, be careful and come back to me safe and sound. Preferably soon so I don't have to sleep without you," you muttered, kissing his cheek. He nodded, throwing a shirt over his head and sliding on pants quickly.

"I'll be back soon, I love you," he said, rushing out the door. You heard Derek laugh and clap Spencer ok the back.

"Nice hickey man," he teased as they stepped into the elevator. You blushed and flopped onto the bed, knowing Spencer was as red as a beet right now. Marriage? Could you see yourself with him forever? Yes. But people would think it's too fast, you knew they would talk. You sighed and picked up your phone, calling the first person that came to mind.

"Hey Nate," you said softly.

"Hey beautiful, what's going on?" He retorted, making you roll your eyes.

"I just needed to talk to someone. It's relationship stuff and I would've called Lola but she's stressed out of her mind right now and I didn't want to bother her."

"Spill, I'm listening. What's new with you and the good doctor?"

"Spencer said he wants to marry me someday," you said plainly.

"Ok? And?" Nate asked.

"What do mean 'ok, and?'"

"Y/N, I love you. You're one of the smartest people I know. But you are oblivious when it comes to social interactions."

"Huh?" You asked, confused.

"He loves you. You can see it by how he acts, how he talks, how his eyes light up. I'm a guy and I noticed it."

"Yeah but what does that have to do with anything?"

"If someone loves you that much, then you've found your forever. I'm sure that one day, maybe not today or tomorrow but soon, he's going to ask you to marry him. And you're going to say yes, you're going to marry him."

You smiled, thinking about it, about spending forever with Spencer. "Thanks Nate."

"Anytime. Now, don't worry about Spencer. You two are solid. Solid as a rock," he reassured you.

"I love you, thank you for keeping my thoughts from running amuck."

"I love you too. Goodnight," he said, ending the call. You smiled, falling asleep to thoughts of Spencer. You felt him slide into bed, wrapping his arms around you. You shifted, curling into his arms. You saw him smile softly, kissing your forehead.

"I love you," he whispered as you fell back into your deep sleep with your arms wrapped around his abdomen. Nate was right. You two were solid.
