A/N: This story has taken on a life of its own! I never really expected it to go this far, but I think there's probably still 2 chapters to go! *sigh*

The morning of Barry and Iris' wedding arrives and Sara and Leonard are lounging in bed.

"Did you ever think you of all people would be attending Barry Allen's wedding?" Sara asks.

"Of course not! I'm just glad you get to be my plus one," he replies.

"Technically, I think you're my plus one. To be fair, when the invitation came through, they all thought you were dead."

"Hmmm, but I'm much more acquainted with Team Flash. If Queen ever gets his head out of his ass and marries Smoak, I'll be your plus one for that."

"Really? Putting conditions on the plus one status?"

He smirks at her and rolls over to the bedside table, fishing out a box.

"Well, how about we do this instead?" Leonard begins as he opens the box. "How would you feel to just always being each other's plus one?"

Inside the box is a beautiful white gold ring with a huge diamond in the band, a white opal and a brilliant sapphire on either side.

Leonard's face is somewhere between smiling and terrified. "What do you say, Canary? Will you marry me?"

Sara is in disbelief. She never expected this to happen, let alone on this trip!

"Yes! Of course, yes!" she answers.

Leonard happily slips the ring onto her finger and kisses it.

Sara smiles at him and then looks at her hand. "Looks like I'll have to move this ring now," she says as she takes Leonard's pinky ring from her middle finger and puts it on the other hand. "Don't want them clanging together."

"Yes, I recall how you hated that noise." He looks to his old ring for a second. "So, how did you get it anyway? I left it on Mick's desk."

"Once we got back from the Oculus, Mick tossed it to me. Growled at me (in her best Mick voice), 'Here. Won't fit my fat fingers.' And walked away.

Leonard laughs. "That was a decent Mick impression."

"Thanks. And I've been wearing it ever since. If you noticed me wearing it, why haven't you asked sooner?"

"Too afraid I guess."

"The mighty Captain Cold? Afraid?"

"Haha, laugh it up. But I wasn't sure what it meant for us."

"Len, we've been sleeping together since you got back. I'm pretty sure it was safe to assume I had feelings for you."

"Normal people would assume that. You know how I was raised. I don't do feelings. At least, not until very recently."

Sara smiles at him and puts her hand on his cheek.

"So, I thought you weren't here to steal thunder. Proposing might be a little thunder-stealing," she says, wondering how the soon-to-be-wedded couple would react.

"Assassin, please. This is the event of the year in Central City! I have to steal something," he says, his smirk in full effect.

"You are one hell of a thief after all."

"Indeed, indeed."

Sara looks to the ring again. "It really is beautiful. You have good taste."

He leans over to kiss her. "Yeah, I do." He lays her back to the bed and they celebrate their future.

After a beautiful wedding, the Legends are all seated at their table with Lisa, who looks very nervous.

"Trainwreck, what's wrong with you tonight?" Leonard questions.

Lisa jumps. "What? Oh, nothing. I'm fine."

He tilts his head at her. "Try again."

"Ok, look. I didn't know how you would react, but I need to tell you something."

"Oh God, are you pregnant?"

"What? No! No, but I do want to tell you that I've found someone," Lisa replies.

"Oh really? Who's the lucky guy?"

Lisa points to Cisco at the bridal party table.

Leonard sighs. "Ramon?!"

"Yes, Ramon. He's a great guy, Lenny. He treats me like a princess."

"As you should be." He drops his head and takes a deep breath, resigning to what's happening. "And you're not pregnant?"

"Give me some credit, jerk."

"Ok, ok. If he makes you happy, then… that's great."

"I knew you'd approve!"

"And just how did you know that?"

Lisa smirks. "Yeah, someday you'll know."

Leonard is just about to question that statement when Sara returns. "Care to dance, Leonard?"

"Do you think it's wise? I'd hate to start a bar fight at Barry's wedding."

"I'll take the chance. Besides, it's a slow dance." She bends to whisper in his ear. "All you have to do is put your hands on me."

Leonard quickly stands. "Lisa, see you in a few." And he allows Sara to lead him to the floor.

Seeing the opportunity, Cisco runs over and sits by Lisa. "So, did you tell him?"

"Yeah. And he took it surprisingly well."

"So, I probably won't wake up as an ice cube?"

"If you continue to be a good boy, I'd say you're in the clear."

Cisco visibly relaxes.

Martin pats Cisco's shoulder. "Everything all right, Cisco?"

"Yeah, yeah. I just found out that Snart isn't likely to kill me for dating his sister."

"You two are together! Mazel tov! Young love is burgeoning everywhere!" He nods to the dance floor where Ray and Lily are sharing a dance.

"And that's not freaking you out, Professor?" Cisco asks.

"On the contrary, Mr. Ramon. My daughter is literally a gift I didn't think I would get. How could I begrudge her any happiness? And Dr. Palmer is a good man. I believe they challenge each other intellectually and he respects her. That's all a father can ask for. Besides, he knows that I'm one half of a nuclear superhero. So, that helps," the professor adds with a wink.

Cisco laughs. It's a little different considering his girlfriend's brother is a reformed super villain, but he's glad to see more happiness for the Legends.

Jax stands at this. "Well, all this talk of young love has inspired me to go ask that beauty over there to dance!"

Nate and Rip have resigned themselves to the bar, declaring their bachelorhood. Amaya and Mick are content to sit, snack, and drink, basically ignoring the others.

Meanwhile, on the dance floor, Sara is smiling up at Leonard. "I'm glad you learned to dance."

"Anything to keep you close, Canary."

"Think anyone has noticed the ring?"

"I'm almost certain the professor has, but I think he's waiting to let us announce it."

She puts her head against his chest in response and he kisses the top of her head, swaying contently.

As the song ends, YMCA comes on, and Leonard declares there's no way he's dancing to that. He, Sara, Ray, and Lily return to the table. They laugh at Jax's antics on the dance floor and grin as they see Ray and Lily snuggle close.

Sara idly drums her fingers on the table, not realizing which hand she was using.

Until Lily realizes.

"Sara! What is on your finger?" Lily screeches.

Sara can't help but smile as she raises her hand. "What? This old thing?"

Leonard is now beaming as well. "Just a little bauble I got her."

"Mr. Snart, am I to assume you've proposed marriage to our Miss Lance?" Martin asks.

"Gonna have to call her Captain Snart pretty soon," Leonard replies. "If she wants, that is."

"I kinda like the ring to it," Sara says.

"Lenny!" Lisa squeals. "I'm so happy for you!" She runs over to her brother and hugs him. "And Sara! I've always wanted a sister!"

Sara pauses, realizing once again she's without hers. But she can't let that take away from her and Leonard's (and Lisa's) happiness. "Thanks, Lisa!"

As the Legends all congratulate the couple, the commotion catches Barry's attention. He and Iris walk over to the table.

"What's all the ruckus over here?"

"Oh hey, Bar!" Leonard says casually. "Sara and I are engaged."

Barry can't help but smile now. "What? Congratulations!"

Now Oliver and Felicity have come over. "Everything ok?" he asks.

"Leonard proposed and I said yes," Sara tells him, holding up the ring.

Felicity squeals and grabs Sara's hand. "Oh my God! It's beautiful!"

Soon, every superhero team member in the room has surrounded Leonard and Sara, providing handshakes, hugs, and thumps to the shoulder.

Thunder effectively stolen.

Leonard sneaks away in all the uproar and once he's back, he's asking Sara to dance.

Before she can answer, the DJ announces, "Hey, this one is for the newly engaged Sara and Leonard. He loves you very much, Sara." And "Love Will Keep Us Together" begins to play.

She accepts the hand he's offering and they leave their friends for the dance floor.

"Really, Len?" she asks as they begin to dance.

"Thunder just a little bit more stolen," he says, smirking.

"What will you do if someone pulls this at our wedding? Ray or even Cisco?"

"Raymond and Cisco will both be put on notice that they will be doing no such thing." He spares a glance to Mick and Amaya, feeing each other strawberries. "Mick as well… just in case."

Sara lays her head upon Leonard's chest once more as they dance to their song, excited to see what the future might hold for her… and him… and her and him.
