Most of the times, craziness lead to wrong decisions, but you can't spent your entire life without taking any risks. There's no fun in that. Some couples spend months planning their weddings step by step, minute by minute and in less than a year, they are already divorces. However, some couples just do it: get in a car, drive to that small church in the pouring rain and their marriage lasts forever. Whether you have a big planned wedding or a small ceremony with four people, that's not what makes it last. It's about trust, love and commitment.

Leonard fell for Penny the moment she walked through his building. First, because of her looks but then because of the little things: the way she smiles, her honesty, her strength and every single thing about her. For Penny, it was a little harder. First, he was just a very sweet guy, a good neighbor and an amazing friend. After a little while, he became the cute nerd with a crush on her. That crush became mutual and they fell in love. They fought, broke up and got back together. Now, they are happily – at least for the most part – engaged and only a few steps from the big day.

Of course weddings aren't simple or easy. They have to plan every single second and considerate all the possibilities, good or bad. But sometimes the pressure is so big that a couple start to joke about dropping everything and just running away. Well, that's exactly what Leonard and Penny did.

- Wow, there's a Denny's in Vegas you can actually get married in.

- Doesn't sound very romantic. Yeah, but we could get heart-shaped pancakes.

- I'm sure we'll find a decent chapel.

- Yeah.

After that talk, there were two distinct possibilities: number one, they laugh and just let the idea fade away as a joke; number two, they stare at each other for a moment and, almost synchronized, get up and make a run for it. Penny and Leonard choose number two.

- This is crazy!

- I know!

- You think people are gonna be mad?

- Maybe. But this isn't about them, it's about us.

- It is. It is about us.

That's just amazing. Their hearts were skipping beats, that was it. No regrets, no comebacks. In a few hours they were gonna be married for real and that was really scary. But I guess that if you have the love of your life by your side, there's nothing to be scared of. Right? Wrong. Even when happiness looks to be ahead of you, if you start to look you'll definitely find something to hold your back and change your mind. Sometimes you suddenly get inexplicably annoyed by the way he or she brushes their teeth, but sometimes is so more complicated than that…

- Uh, well, there... there's one thing I feel I should tell you. - When Penny heard those words from Leonard in the car on their way to get married she finally felt that scare.

- What?

- You know, so we can go into this with no secrets between us.

- What?

- Remember, uh, a couple years back when I was on that research ship in the North Sea?

- Yeah.

- Okay, well, there... there was a lot of drinking and craziness going on...

- No, you told me.

- Okay, um… Well, there was this girl. - Penny lost her track of time. She had no idea how much time passed during that conversation, but it has one of the hardest things she ever had to hear.

- What did you do?

- Nothing… - She wanted to believe in Leonard, for real, but that's not how feelings work. You can't just turn it off and pretend it's not hurting anymore. - Really. It was just kissing.

- And then what?

- And then nothing. - "Oh my God, why didn't him just told me before or not told me at all? He just made it a damn big deal", Penny thought. - I stopped it. But it still bothers me, and… I wanted you to know.

- All right. - Penny really wished to say something else, she tried to tell Leonard it was fine, it wasn't bothering her at all, but it'd be a lie. She was devastated and lost wanting everything to just stop but her mouth was opening and closing and no words were coming out.

Leonard asked her what he could do to make things better, but she didn't know how would fix things or even if there was a way to fix. How do you get over something like that? Cheating is still cheating; distance, loss, loneliness, revenge… there is no excuse whatsoever. And the place Penny was feeling more hurt was heart because she was ready to give it to Leonard, but now she had doubts.

They got to Vegas and the wedding was still on. Penny wasn't talking about what happened e Leonard wouldn't push it. They went through with it. The ceremony went on and it was as good as a Vegas wedding can be.

"Penny, we are made of particles that have existed since the moment the universe began. I like to think those atoms traveled 14 billion years through time and space to create us, so that we could be together and make each other whole."

Leonard's vows were so beautiful that, for a moment, Penny forgot everything about that stupid talk in the car. For a single moment all she could feel was the joy of being loved for such a kind man. She tried her best to say something "mushy", but it wasn't that good. Leonard didn't care; for him, getting to walk with Penny in his arms as his wife was all he really needed to be happy.

Unfortunately, their honeymoon ended before it even started. Leonard did carry Penny through the door, but the magic stopped the moment they kissed in what was supposed to be their perfect night… She couldn't kiss him and not imagine some random girl making out with Leonard. That was hard on her, more than she could imagine.

Was that gonna be the end of their marriage? Before it even started?

Well, they headed back to Pasadena, but they didn't go home, because that's was an unknown place for now. Penny went to her apartment and Leonard went to his. Each one followed their separate ways, opposite sides of the hallway, together but apart. How long was that gonna last? That was a really difficult question that neither of them knew how to answer.

Penny was trying to find a way in her head to forgive Leonard, but every second was just getting harder. If it wasn't bad enough, Sheldon mentioned the girl his roommate had an adventure with worked with them. That only made things worse.

"In top of everything, how could he not tell me that? I was convinced that was just a kiss, now I'm not so sure. Oh Leonard, you drive me crazy", Penny was sitting on the couch, trying to figure out her next step. She fell asleep after a couple hours. Maybe the next day had something better for her.. Maybe.

In the apartment 4A, Leonard kept rolling in bed and going trough everything that happened in the night he kissed the girl. Then he started thinking about the talk in the car. "Oh my God, I'm so stupid. How can someone so smart do something so stupid?". He didn't know what to do. He thought about going over there and talking to Penny, but what would he say? There wasn't a right or easy answer for his problem. Then, he cried himself to sleep.
