Penelope pushed away from him roughly and turned her back to him, as the once happy tears now flowed freely full of angst.

Derek grabbed her arms and pulled her back to his chest, spinning her around so that she was facing him again. He used his finger to lift her chin so that she was looking in his eyes. She looked at him with wide eyes as she let the tears flow unashamed of her disappointment. Her face made his chest clench in pain. He never wanted to hurt her. "Listen to me, Penelope Garcia. I do love you, but I've got to end things with Savannah before I even want to go there with you. It's not going to be as easy as a phone call. I owe her more than that. Obviously I got carried away last night and this morning."

Sucking in a deep breath to calm herself down, she nodded her head. "Yeah… ok. Um, I'm going to take a shower. Just lock the door behind you when you leave. I'll see you at Rossi's." She didn't leave him any room for argument as she walked away, closing and locking the bathroom door behind her.

The cab pulled up to Derek's house. Savannah's car was parked out front, and he knew there was going to be hell to pay on the other side of the door. When he had finally checked his messages this morning, he had 3 voice mails, each escalating in anger, and 14 very blunt text messages. Sam was not the only one unhappy that Derek stayed at Penelope's apartment.

Sadly, Derek had never even thought about texting or calling Savannah last night to let her know he wouldn't be home. He was so wrapped up in Penelope, Savannah never even crossed his mind. When he realized his mistake this morning, he was ashamed. He knew that deep down he loved Penelope, but he was with Savannah. Hid did care for her. How could he have totally forgotten her?

She was on call but that didn't mean she couldn't be at home that night. She understood his job and they had worked so hard to get to a place where they understood each other's absences, but she knew he wasn't working last night. She knew last night was just fun. She knew last night he had no reason not to come home. She knew that he'd be with Penelope. He knew that she had every right to be furious with him.

Savannah was always secure in her relationship with Derek and was never jealous of his friendship with Penelope. She saw their affection as familial. Penelope was always so gracious to her and tried her best to help them iron out their differences when she could. But in the back of her mind, she was jealous of how easy they were together.

Of course, she had expected easy communication after a decade of friendship. However, Derek and Penelope had something she couldn't put her finger on. They just knew what the other person needed at all times. Sometimes it was calling the other on their crap. Sometimes it was sympathy. Sometimes it was making the other laugh. Sometimes it was just a silent hug. Penelope always knew what Derek needed. Always.

After close to two years together, Savannah thought she knew what Derek needed. Sadly, she was wrong more than she was right, and that usually resulted in distracting him with their physical relationship instead of helping him deal with things. Everything with Derek was so hard. Sure relationships required work, but why was this one so hard?

When they moved in together, she thought for sure that their time apart and communication issues would end. They didn't. In fact, being around Derek all the time made it even more evident how they didn't quite fit together, even though they were trying so hard. Had their relationship been so damaged by the last several months that he hadn't even thought to let her know where he was? She may not have been able to answer his call, but a simple "crashing at Pen's" text would have been sufficient, even if it would have irked her. Cabs run to their house, just like they do to Penelope's apartment.

It wasn't like she'd hadn't gone long periods of time without hearing from him. That was expected given their jobs. It wasn't even the first time he'd slept at Penelope's apartment, but he always let her know what was going on. What was different now?

Derek walked into the house and found Savannah sitting on the sofa just staring out the window. She appeared to be deep in thought.

"Hey" he said somberly.

She turned to look at him but didn't say anything. She wasn't really sure what to say at this point. She was angry with him, and she was hurt; but she absolutely did not want to have a heated argument. Right now she just wanted an explanation.

"Why am I so easy to forget? I live with you, dammit!" Her voice showing the anger that she was trying to keep from her expression. Trying to regain her calm, she quietly added, "What the hell happened last night?"

Derek's voice caught in his throat as he collapsed on the chair across from her. He was going to hurt her, and he didn't want that. She wasn't the one, but he never wanted to hurt her. "We went out. We had too much to drink. I crashed at Garcia's. It was closer, and I was really drunk. I'm sorry I didn't let you know where I was."

"Ok. So what really happened?" she countered. Derek may be the profiler, but she could tell when he was holding back. He was definitely holding something back.

"That's what really happened." He replied with his blank expression firmly in place.

"Ok. We'll stick with that for now. So let's answer the other question. Why am I so easy to forget? We've been together for two years, Derek!"

"Savannah, look…" Derek trailed off not knowing what to say.

"Don't give me a line of crap, Derek. We've worked too hard on this relationship. If there is something going on… if there is someone else, then just say it." She choked out, her anger now turning to sadness at her thoughts. Swallowing the lump in her throat, she continued, "If you want out, then you say so. Man up and decide what you want because the passive aggressive stuff to make me break up with you is so last year. We've been there… remember?"

Derek sighed deeply and dropped his head. Gathering his thoughts, he finally picked up his head and looked at her. "Savannah, I do love you. I just don't love you enough."

"What the hell does that mean?" she yelled, her anger now coming out as she let go of her previous attempts to keep her temper even.

"There is someone else. I have not physically cheated on you, but someone else has total ownership of my heart." He confessed. The last thing he ever wanted to do was hurt Savannah, but he had to be honest with her.

"Who?"

"It doesn't matter."

Taking a minute to think about the last couple of months, there were only a couple of people he spoke to regularly outside of work other than Savannah. At that moment, a lightbulb went off in her head. "It's Penelope!"

"Yes." He whispered.

"I trusted you! I trusted that she was only your friend! Every one said I was a fool to let you stay friends with her, that y'all were too close. But no, I was all 'Oh it's just Penelope! She's like his sister!' I'm such an idiot! How long has this been going on?" she demanded to know.

"I told you that nothing is going on, but I can't continue with things the way they are. Do I want something more with Penelope? Yes, I do. I always have, but I'm not good enough for her. And right now, I don't even know what she wants, but I owe it to you to be honest with you."

"Wow." She looked at him with complete dismay and shock. "So you're not good enough for her but you are good enough for me? And you've always wanted her. What the hell have I been, Derek? Am I a two year experiment to see if you can handle commitment?"

He didn't know what to say. He'd never ever considered his subconscious motivations for his relationship with Savannah other than his attraction to her and need for a companion. He had absolutely no idea what to say. This was not at all how he expected this talk to go.

Savannah took his silence to mean that she'd been correct. "Give me a week and I'll have my stuff out." With that, she headed up the stairs to get away from him.

"I'm sorry!" he called to her retreating figure. He had no words for his current situation.

"Me too." she whispered to herself as the tears began to fall once she shut the door.

Knowing he needed to clear his head, Derek went for a run. Hopefully it would help him gain some perspective on the situation. When he returned, Derek showered in the guest bathroom and grabbed his go bag from his truck. He didn't want to invade Savannah's privacy. He also didn't want to see any pain on her face. He didn't consider himself a coward, but he felt like one right now.

His run had helped him. Not only did it help him get rid of any residual alcohol from his system; but he also was able to gain some perspective on the whole situation. He never wanted to hurt Savannah. She really was important to him. She was his longest relationship, other than Penelope of course.

Even if Penelope didn't want to be with him, Derek knew he had to end things with Savannah. How could he be so wrapped up in someone else to completely forget about her? It wasn't fair to her. Ignoring his true feelings had obviously not worked. He did what he had to do.

The drive to Rossi's house seemed twice as long as it normally was. Derek wasn't sure how Penelope was going to react when she saw him. Was she going to pretend nothing had happened? Was she going to keep her distance not knowing what had happened with Savannah? He had texted her that he was on his way like always, but her response was only that she would see him there - no hearts, no smiley faces, no cheery sayings. He honestly didn't know what to expect. She had to understand that he had to talk to Savannah first. Didn't she?

As she locked the bathroom door behind herself, Penelope started the shower to drown any sound of her tears. She knew Derek would see himself out and not try to interrupt her. She knew he would understand what she needed. She needed to be alone with her thoughts, with her guilt.

When she stepped into the shower, her tears blended into her watery surroundings. How could she forget he was with Savannah? How could she expect Derek to just walk away from his girlfriend of two years that he freaking lived with after one night of sexy karaoke and dirty dancing? She liked Savannah. Savannah had been good for Derek. Savannah had forced him to face so many of his relationship fears. Savannah and Derek had worked really hard to get to where they were. How could she screw that up for him?

With "fake it until you make it" on repeat in her brain, Penelope dressed casually yet cheerfully for the barbeque at Rossi's, deciding on a pair of jeans that she was rarely seen in. Instead of sitting around idly killing time and continuing to torture herself, she decided to bake away her guilt. Even though Hotch said the food was taken care of, a few more desserts never hurt anything.

Three hours later, Esther was loaded with the bounty her heavy heart had produced. In between trips to the car to load the brownies, cookies, cobbler and pie, she hurriedly replied to Derek's text trying to get out the door so she wouldn't be terribly late.

After debating her next course of action, she knew she had to pretend as if nothing happened. No one else on the team knew what had happened. JJ had only sent her a text this morning asking if she'd made it home ok. She responded as she normally would and went on about her business. She wasn't ready for them to know about her break up with Sam, especially given the circumstances.

Given their little dancing show the night before, Penelope also didn't think it was that good of an idea to talk about Derek too much at all. She would do her best to be as normal as possible. Now she just had to figure out what was normal for her and Derek.

She would make sure Derek knew that she would make time for him whenever he was ready, but things would be status quo until then. She couldn't let her heart venture back into that territory any time soon. This morning, when he said he wasn't ready for her yet, it was like her heart stopped. When he explained himself, it was as if a doctor yelled "clear!" ready with the paddles to shock her heart working again, but the shock hasn't come. Not knowing if or when she could get everything she's ever wanted has left her numb.

She would just fake it until she made it.

A/N: Ok, I'm not trying to be angsty at all. I just think that ending the relationship with Savannah was going to be a lot more serious than the one with Sam. Thanks for reading!
