Leonard sensed her before he even saw her. He had always been able to do that and this time was no different. The thing that was different this time was that there was a loud warning siren going off in his head blaring, "Extreme danger ahead, warning, warning, proceed with caution!" That had never happened before with anyone, let alone Penny. The only thing that calmed him at that moment was the feel of someone's hand suddenly intertwined with his.

As they walked up the driveway toward the house, Isabel felt Leonard suddenly tense up and knew something was wrong. It didn't take long for her to see the cause of Leonard's sudden discomfort. Isabel didn't consider herself a violent woman, but the sight of the person before her made her question that belief. She knew exactly who it was that now stood before her and Leonard and all she wanted to do was to protect him. Without even thinking about it, Isabel slipped her hand in Leonard's to let him know that she was here for him and she would stand by him.

"So, Leonard, who's your new, extremely-close friend?" Penny asked, the agitation in her voice directed at the woman who was holding Leonard's hand.

"Penny, this is Dr. Isabel Fortunato. Isabel, this is Penny Cahill, Wyatt and Jenny's daughter."

Tension was thick as neither woman offered their hand in greeting. Sensing the awkwardness, Leonard said, "Isabel is working with me on some organic farming projects for a few of your dad's friends."

"I bet she is." Penny said, eyeing the woman up and down.

"Penny, what are you doing here? How did you find me? I didn't tell anyone where I was going." Leonard said in an increasingly exasperated tone.

"My mom told me you were here working with my dad when I called her to ask for some advice. As soon as I knew you were here, I flew here so we could talk."

"How could you afford to fly here?"

"Everyone gave me their frequent flyer miles."

"Does everyone include my former friend, Raj?"

"Yes, but that doesn't mean anything. He just wanted to help me get here so we could talk and work things out."

"Just like he wanted to help you and me work things out the night he slept with you in my bed?"

"Leonard, please. I know you're really pissed about that and I'm sorry it ever happened. If we could just talk privately, I know we could fix this."

"What makes you think I want to work things out? Sometimes you find out the dreams you had never had a chance of coming true and the sooner you realize that the better off you are. Sometimes, no matter how much you want something, no matter how hard you try, no matter how patient you are, sometimes things just aren't meant to be. I think you and I are one of those things. Now if you'll excuse me, Isabel and I have some data to analyze so we can report our findings back to your dad's friends."

Leonard and Isabel made their way around a very surprised Penny and continued walking until they disappeared inside the house.

Well that went well, Penny thought to herself. I thought he'd say he hated me and never wanted to see me again. You're wrong about us though, Leonard. We're meant to be together and I'm going to prove it to you.

No matter how hard Leonard tried, he simply couldn't get to sleep. The events of the last few days and the various conversations he'd had with Wyatt and Jenny and Isabel kept cycling through his head with seemingly no end in sight. If he hadn't been awake already, he never would've heard the doorknob to his room slowly turning. Leonard leapt from his bed and hid so whoever was trying to come in to his room wouldn't see him, especially in the dark. Leonard watched as the intruder made their way over to his bed. They paused beside it for just a second as though they were listening for something, then lifted the covers up and started to get in. It was at that same moment that Leonard turned on the light in the room startling both him and his uninvited nighttime guest.

"Penny, what are you doing?"

"Uh, trying to make it into the neutral zone without being detected; I guess I wasn't successful."

Leonard looked at his former girlfriend and couldn't help but laugh.

"No, I mean what are you doing in here, in my room, in the middle of the night?"

"Well, you wouldn't talk to me when I arrived. You barely said two words to me at dinner, and you wouldn't even look at me much less talk to me the rest of the night. Then, without warning, you just disappeared and we figured you were hiding in your room. So, I thought I'd just sneak into your room and make you talk to me."

"Penny, I don't know what you want me to say. Do you want me to say how heartbroken I was when you broke up with me with virtually no explanation? Do you want me to say how hard it is just being friends with you? Do you want me to say how jealous I am of the other guys you were with? Do you want me to say how devastating it is knowing you moved on from me so quickly? Do you want me to say how pathetic I feel waiting for just an inkling of a sign from you that you might possibly be interested in me some day, but all the while knowing you never will? Is that what you want to hear?"

Penny stood there staring at Leonard with tears pouring from her eyes. She tried talking, but nothing would come out. Finally, she was able to voice the words she so desperately wanted Leonard to hear. "No, I just wanted you to know how sorry I am for everything that I did. I shouldn't have broken up with you. I shouldn't have dated anyone else. I shouldn't have slept with Raj in your bed. You'll never know how sorry I am for hurting you. You're a wonderful and honorable man. You didn't deserve anything that I did. I don't have any excuses for my behavior. I only hope that in time you'll forgive me."

Time seemed to slow down and Leonard knew this was one of those defining moments in his life that he had heard others talk about but never experienced himself. His mind and his heart processed everything that had occurred between he and Penny since the moment they met. He had processed all the possible variables involved in their relationship and they all led to the same conclusion. The shocking thing to Leonard was the outcome of their relationship was so clear, but he had either never seen it or somehow refused to see it. Yet, there it was.

"Penny, I forgive you, but it's over between us."

Marie, just stared at her dad and said, "That's it? It was over just like that? There were no broken hearts, no repercussions, nobody's car got keyed, nobody got trashed on social media, nothing?"

"Marie, honey, of course there were consequences, but don't you think it was for the best?"
