Martha felt at ease now that the boys were on speaking terms again. As luck would have it, their reconciliation timed perfectly with the boys' sacred annual Vegas pilgrimage. Martha had always wondered what Las Vegas was like. Now she finally got to see it for herself.

"I hope Sam is having fun," Martha commented as she lay next to Dean in bed.

"He's the one that decided he'd rather go off on some granola munching hike in the desert by himself instead of staying in a luxury hotel for once," Dean replied.

Martha rolled onto her stomach and rested her chin on Dean's bare chest. "Could it be your choice of lodging?"

"This place is freaking awesome," Dean protested. "There's a roller coaster, mini golf and did you taste the pie on the buffet?"

"Which pie? There was more than one."

"Exactly!"

"Do I need to remind you that there's also an abundance of clowns?" Martha asked.

"Is it my fault Sam is acting like a little bitch?"

"Jerk," Martha replied playfully on Sam's behalf.

Dean's phone began to buzz and he retrieved it from the nightstand. He looked at the screen and saw that Sam had sent him a text.

"Sam?"

"Yea." Dean nodded as he read silently. "He's down the road. Wants us to meet him." He paused. "'Wear a suit,'" he read the message out loud.

"Case?" Martha questioned as she reluctantly pulled herself away from Dean in order to get dressed.

"Must be," Dean answered as the two of them crawled out of bed and prepared for whatever awaited them at the mysterious address that Sam had sent.

"Sam's married," Martha marveled.

Dean exhaled sharply. "Yep." When Sam called them to the wedding chapel, he naturally assumed it was for a case. Not an impromptu wedding ceremony.

"To a stranger," Martha continued.

"Well…"

Martha looked at him seriously. "So the two of you know this Becky?"

"I know all about the two of them." Becky answered eagerly. "I'm Sam biggest fan!"

Martha stared at Dean. "Hunters have fans?"

Dean groaned softly. "It's a long story."

Becky looked at Martha with wide eyes. "You mean you haven't read the books?"

"There are books?"

"Oh my God, yes!" Becky replied excitedly. "The Supernatural books changed my life." She looked at Sam lovingly. "I couldn't believe it when I realized that Sam was real. It was like a dream come true. And now I'm Mrs. Becky Rosen-Winchester!"

Becky sighed softly once the annulment papers were signed. Martha hung back once the boys left the room with Garth, a quirky hunter Bobby had sent along to help them with the crossroads demon that Becky made a deal with.

"It gets better you know," Martha told Becky. "I was like you once."

"How?" Becky looked at her. "You have your very own Winchester."

"Not Dean. Before him," Martha clarified. "There was the man that I was mad for. He was…impossible. He was clever and a bit dangerous and gorgeous." She laughed to herself. "But as strongly as I felt for him, he never felt the same."

"What did you do?" Becky asked.

Martha exhaled. "Well I lied to myself for a bit. I convinced myself that I was okay with just standing next to him. That it was just as good. Then I realized I wasn't being fair."

"To him?"

"To myself," Martha replied. "So I moved on. It wasn't easy and I'll admit I slipped into those old feelings once or twice, but one day I woke up and realized that I deserved better. I deserve someone that loves me as much as I love him. You'll get there one day too, Becky."

"So just do me a favor," Dean looked at Sam. "Next time we go to Vegas, can you try not to pull a Britney?"

Sam rolled his eyes. "Are you done?"

"I figured you'd get married first, but I thought it'd last a bit longer," Dean teased.

"Really?" Sam leaned against the car. "The way things are going with Martha, I would have thought you'd be ready to drop down on one knee by now."

Dean scoffed softly. "Me and Martha? Married?"

Sam shrugged. "You're practically there already. I've shared motel rooms with the two of you. You're like an old married couple."

"No we're not, because we still have sex," Dean countered.

Sam winced. "Again, I've shared motel rooms with you."

"It was only the one time and we thought you were asleep."

"And deaf apparently." Sam shook off the thought of Dean and Martha having sex. "The point is this thing with Becky wasn't real, but it doesn't mean I wouldn't marry a girl if she was the right one. And I think Martha is your one."

"Even with all this crap we deal with a daily basis?" Dean questioned.

"Because of that," Sam insisted. "The life of a hunter short and dirty, Dean. Martha knows the deal. She's smart and she gets better at hunting every day. I mean she's seen our lives and she hasn't run screaming back to England. I don't know if that makes her crazy or what, but if I were you I wouldn't let her go."

"I like Becky," Martha told Dean once they had checked into a motel for the night.

Dean laughed. "Are you friggin kidding me? Chick's insane."

"She's a bit…intense, but I think she's a good person deep down."

"Way down," Dean joked.

"We've all done crazy things for love," Martha retorted as she pulled her shoes off and sat on the bed.

"What have you done?" Dean challenged.

Martha let out a laugh. "Which time?"

"Been in love that many times?"

"No, but I thought so at the time." Martha stretched her limbs and lay back against the bed. "I mean it felt real, but hindsight is 20/20."

"What about this?" Dean asked. "Is this thing between us real?"

Martha turned her head and looked at him. "Are you serious?"

Dean shrugged. "It's just a question."

Martha sat up. "Of course it's real, Dean."

"But how do you know?" Dean sat next to her. "How can we be sure that…that this is really it?"

Martha sighed softly and took Dean's face in her hands. "Because you're my destiny, Dean."

"You never struck me as the destiny type," Dean quipped.

"It's because I know our future. Well sort of," Martha told him.

"The Doctor?"

"Do you remember Amy and Rory? And how the Doctor mentioned that timeline where Rory and I got married?" Martha asked.

Dean arched his brow. "Is this going somewhere?"

"Yes," Martha assured him. "Before everything went back to normal with our timelines, I met this someone. She was Amy and Rory's daughter from the future and a time traveler like the Doctor. Well she told me that we would meet one day in hospital in America. River told me that we'd fall in love."

"Wait, did you say her name was River?"

Martha nodded. "Well her real name is Melody, but she goes by Dr. River Song."

Dean frowned. "When you were in the hospital, there was this British chick that said she was checking on you for some doctor friend. She called herself River."

"Big blond hair?"

Dean nodded. "Did we get Parent Trapped?"

"That's how she knew. She knew we'd be together because she had already seen it. She saw you."

"So we're destined," Dean repeated her words.

Martha nodded. "I think so."

Dean let out a slow breath. "Okay. That should make this easier then." He slid off the bed onto the floor.

Martha scooted over to the edge of the bed and looked down at him. "What are you doing?"

Dean knelt in front of her on one knee. "Martha…" He took her hand even though he didn't have a ring for her yet. "I can't promise our life will be perfect. Hell I can't even promise to keep you safe. But I can promise to love you until the day I die, whenever…and how often that may be."

Martha was stunned into silence. "What?" she managed finally. "What exactly are you saying here, Dean?"

"I'm saying…" Dean exhaled. "Martha Jones, will you marry me?"
