Soon enough, the wedding of Sara Lance and Leonard Snart comes and goes. Lisa has yet to reveal that she knew about it long before anyone else, but she has had a fun time making her big brother wonder just what she was talking about sometimes.

And Barry finally figures out why Leonard said not to sit him at the singles' table.

Cisco proposed to Lisa one week after Leonard and Sara's wedding (far too scared to disobey the marching orders to do no such thing at their wedding).

That night, after the friends met to celebrate the engagement, Leonard sits with his head in his hands.

"Still feeling the stress of having Cisco for an in-law?" Sara asks, rubbing his shoulders.

"No. I mean, yeah, but there are so many worse guys out there for her. So many villains she could have fallen in with. This is good for her. I just wish he wasn't so annoying."

"He's an acquired taste, but his heart is in the right place."

Leonard just nods. "She asked me to walk her down the aisle."

Ah, so that's what this was about.

Sara sits next to him. "And you said?"

"Of course I said yes. But it's not right. We shouldn't be doing it this way. My father should be doing that. He should have been a better father, he should have loved us and been there for us and not taken his failures out on us. I shouldn't have had to put him down because he almost killed my baby sister. He should be doing this."

His tone is flat, but Sara hears the subtle rage under it.

"Len, no one would ever tell you that you're wrong about any of that. Your father doesn't deserve another thought and he wouldn't have deserved the honor of walking Lisa down the aisle. You raised her, you get that honor. And you can give Cisco one of those death grip handshakes at the altar."

Leonard chuckles. "You're right, assassin. You almost always are."

"Almost?"

"Well, you did wait until my impending death to kiss me."

"Hey! You certainly didn't—"

He interrupts her argument with a kiss. Even though he knew he'd pay for that later.

A year later, the day of Lisa's wedding arrives. Sara, Caitlin and Iris stand with Lisa, while Barry, Julian and Leonard stand with Cisco.

Right before Leonard walks his sister down the aisle, he walks up to her. "Wow, sis. You clean up pretty well."

Her off-white gown with gold accents is stunning.

She smirks at him. "You don't look bad yourself. Sara dress you today?"

"What can I say? She's a sucker for me in a tux."

"She must really love you to put up with you."

"I could say the same for Cisco." He leans down. "You know, it's not too late to skip out on this."

"Leonard!" Lisa hisses.

"Kidding, kidding! Listen, I couldn't be more proud of you. You know that, right?"

Lisa beams up at her brother. "Yeah, I know. And I'm pretty proud of you too. You've made a pretty good life for yourself with an amazing woman."

Leonard begins to walk them towards Cisco. "Yeah, I have. And you're about to make a great start with a good guy too. Who would have thought we'd have made it this far?"

Lisa chuckles. "Not me."

He pats the hand that's placed on his arm. "Just remember, if he ever hurts you…"

"The Cold Gun is never far away."

"Yes."

They reach the nervous groom and Leonard shakes his hand with a very firm grip. "You be good to her."

"Always," Cisco replies with a genuine tone that stops Leonard for a second. He never doubted that Cisco loves his sister, but he knows it now definitively.

The wedding proceeds and Leonard will never admit it, but a few tears did break lose as he watched his baby sister share vows with Ramon. Sara will never admit to handing him a tissue.

Sara holds Leonard close for most of the reception. He's so happy for his sister that he doesn't really question why she's doing it.

The reception is beautiful, all done in gold tones. Cisco and Lisa's first dance has Caitlin and Iris crying. And Lisa and Leonard's dance has the whole room wiping their eyes.

As Lisa looks around her, seeing friends and loved ones, knowing that she's finally getting her happily ever after, it's a dream come true. She's terrified of waking up and finding out it was all an elaborate dream.

"What's on your mind, Goldie?" Cisco asks as he puts his arms around her from behind.

"Nothing. I'm just so damn happy right now. I never thought I could have this."

"Well, you do. And I'm going to spend the rest of your life giving you everything you want."

She puts her hand on his cheek. "You already have."

"The Golden Gun?" he jokes.

"Yeah. That. No, you weirdo. Your heart. I love you so much, Cisco."

"I love you too, Lisa."

Leonard pretends he doesn't see the kiss they share.

Once they get back to the Waverider, Sara smiles as they undress for bed. "You looked kinda like a proud father today. Especially when you danced your brother/sister dance with her."

"I couldn't help it. We both got out from under our father. I am proud of her. And me. And, dammit, even of Ramon."

"It looked good on you."

"Thanks, assassin. You looked pretty damn good tonight too."

"I'm glad the proud Dad look suits you. It'll be good practice for a few months from now," Sara says as she climbs into bed.

"Yeah, that's for… Wait, practice for what now?"

Sara grins. "Actual fatherhood."
