Spencer hadn't realized how much paperwork he'd let pile up, it was after nine when he got out of the office. When he got to the apartment, Liz came over and gave him a quick kiss.

"Are you hungry?" she asked, "I've got pizza on the way."

Spencer had been so focused on getting the paperwork done, he had completely forgotten about eating.

"Starved," he said, sitting down.

"So, have you planned our date yet?" Elizabeth asked with a grin.

"Derek wants to go dancing," he replied, with a small grimace.

"Dancing, huh," Elizabeth said, with a smile, "Sounds fun, but I have to ask something. Do you dance?"

"Truthfully, I've never tried," he said sheepishly.

"Well, I guess there's a first time for everything." she said with what Spencer could only call a come and get me grin.

He felt his pulse quicken. She was going to drive him crazy, but it was in a good way. He wasn't used to feeling this way, especially not this strongly.

He went up to Derek first thing when he got to work the next day, "You win, we're going to the…club,"

Derek grinned and high fived Spencer, "Alright!"

"Do I want to know what you two are up to?" Emily asked, coming up beside Derek.

"Just making weekend plans," Derek said.

"To do what?" Emily asked, arching an eyebrow.

"Garcia and I are going to a club with Spencer and his new girlfriend."

"Girlfriend?" she practically choked out. "Do we know her?"

"You've met her," Spencer said, rather evasively.

It quickly clicked for Emily, and her eyes widened.

"Tell me you don't mean Elizabeth!" she exclaimed.

It was Derek's turn to arch his eyebrow, he was promptly confused. Spencer however, was just annoyed.

"Yes, I mean Elizabeth," he said, tone already rising, "Why does my relationship with her bother you so much?"

"Oh, I don't know Spencer, maybe because she's only seventeen, or because it's a classic case of transference. You need to be reasonable about this."

"He needs to be reasonable, he's not the one screaming." Derek said, incredulous.

She glared at him, "You can't be okay with this!"

"He's a big boy, Em, they want to be together, why should I be against it. If I didn't know better I'd say you were jealous."

"But you do know better. Not that it matters, I'm trying to talk sense into him, not you."

"Emily," Spencer started, trying to keep his voice even, "I'm not sure what's going on with you right now, but this conversation is over. Elizabeth and I are together and that's not going to change."

"Somebody want to tell me what's going on?" a voice asked from behind the group, causing them all to turn. It was Rossi.

"Nothing," Emily said, storming off.

"Reid, can I see you in my office for a second." Rossi said. Derek and Spencer exchanged glances, before Spencer followed Rossi.

"You want to tell me what that was?" Rossi asked, once Spencer was seated.

"Elizabeth and I are dating, and for some reason Emily has a problem with it."

"Sounds to me like she's jealous," Rossi said, he'd always had a way with brutal honesty.

"Jealous?! Why would Emily be jealous?"

"Have you ever thought women aren't as oblivious to you as you think they are?"

"No, besides Emily is my partner, it's not even allowed."

He couldn't deal with this, he was barely figuring out how to handle his feelings for Elizabeth. The prospect of Emily having feelings for him was too much to deal with.

"Partner or not, these things happen."

"So what do I do about it?" Spencer asked.

"You need to figure out what's going on for sure. The two of you can't go on being hostile to each other, it could effect you too much on the job."

Spencer left Rossi's office. He didn't want to do this, to talk to Emily at all right now, but he made his way over to her desk and sat down.

"Are you going to tell me what's really going on? You don't even know Liz, yet you've been nothing but hostile since you found out she's staying with me. You're my partner and friend, I appreciate you being concerned, but I feel like there's something more going on."

"I don't want to see you hurt, okay. She's seventeen, I doubt she's exactly looking for a serious relationship. You're going to be ready to settle down way before she is."

"Honestly, I've thought about all this Emily, and I would rather take my chances with getting hurt, then not be with her at all. So, are we good?"

"Yeah, Spencer we're good."

Spencer walked back to his desk, why couldn't life be simple?
