"Sara!"

Sara Lance groaned and stirred at the sound of a familiar voice calling her name. She tried to piece together where she was and what had just happened, but her mind was a blank and her body refused to obey her. Every bone in her body ached like she'd just been thrown against a brick wall.

"Sara! What are you doing out here by yourself?"

There was the sound of running footsteps, and then gentle hands were lifting her and turning her over. A sharp gasp, and then the voice that had been warm with concern turned cold with accusation.

"You're not my Sara."

She blinked open her eyes woozily. The face above her was as familiar as the voice, and yet…not. "You're not my crook."

His face was older, more heavily lined. More gray in his hair. He looked a bit scruffy and unkempt, with a small scar marring one cheek, but his eyes… His eyes were the same piercing blue, and they were filled with wonder and reverence and…love. One hand hovered over her cheek.

"How are you here?" he breathed.

Sara sucked in a sharp breath and jerked away from his touch. "Where is here?"

He sat back, hands up as if he were under arrest. There was a flash of hurt in his eyes that he couldn't conceal quite quickly enough.

"Central City."

"Well, that's where we were headed, but this doesn't look like 2018."

"That's because it's 2033," he drawled.

Sara scrooged her eyes shut and rubbed her forehead. "Not again."

Snart picked his way carefully through the debris that littered the abandoned warehouse. He vaguely recollected it as a place he and Mick had once used to plan heists a long time ago. Despite moving with his usual care and grace, a voice surprised him.

"I wasn't expecting you back for another hour or so."

"Sara? Where the hell are we? How did you get here?"

He heard the sharp sound of her staff opening, bare seconds before the tip was at his throat.

"You're not my Leonard."

She stepped into his field of vision. Something was slightly off about her movements. She moved into the light, and he gasped harshly. There were threads of silver in her hair, and the right side of her face was lined. The other was…well, he'd been around Mick enough to know burn scars. There was clearly no vision in her left eye.

"What happened?"

"If you were my Leonard, you'd remember. But you're not him…you're…young."

He glanced around. "I know we're in Central City, but when are we?"

"2033."

"Fifteen years. And we're…together?" Sara asked.

Leonard looked down at her, still with that soft look in his eyes. "Meeting you - her - was the best thing that ever happened to me."

"Now I know you're not my crook."

He chuckled softly. "He still pretending he doesn't have any feelings?"

"Sometimes."

"He's an idiot. So're you, if you let him get away with it."

He was walking on Sara's left side, and she frowned when he tried to take her arm to guide her around some debris. They both heard very familiar voices up ahead and quickened their steps.

Leonard strode quickly to his Sara's side. He cupped her face in his hand and pressed a kiss to her temple.

"All right, beautiful?"

She chuckled softly at that. "I am now."

"What happened here?" the younger Sara wanted to know.

"Probably best not to say," her counterpart replied.

She stepped into the light, and the two women contemplated one another.

"Why didn't you have Gideon heal you?" Sara asked softly.

Older Leonard pulled his Sara tight against his side. "Probably another thing we shouldn't discuss."

"Is there anything you can tell us?" younger Len asked, crossing his arms and leaning against a convenient doorframe.

"I could," his counterpart replied. "Not sure if you're smart enough to listen."

His Sara elbowed him. "He's you. He's smart enough."

"He's me, fifteen years ago."

"He's standing right here," the younger Snart reminded them.

Older Len tucked his Sara just a bit tighter against himself. "There's exactly one thing you need to get through anything this universe - or any other - throws at you. She's standing right beside you."

The younger couple eyed one another speculatively. They weren't exactly averse to the idea.

"Any idea how we -" Sara began.

There was a flash of blindingly bright blue light, and the older couple found themselves standing alone in the ruined warehouse.

"Think they'll figure it out?" Sara asked.

"She may have to explain things to him a few times," Snart replied, smirking at her, "but I'm sure he'll catch on…eventually."

"Snart! Sara!"

Snart forced himself to his knees and shook his head to clear it. He was on the bridge of the Waverider. Raymond was waving a device of some sort in their general direction - presumably, whatever had grabbed them back from wherever they'd been. And Sara…

He staggered to his feet and over to her side, carefully helping her to stand. He brushed her hair back from her face and sagged in relief. Her face was young and unmarked. Two bright blue eyes stared up at him.

"What the hell was that?"

"I don't know," he replied. "Was it even real?"

"It felt real," Sara replied.

"Too real."

They were still standing very close. Len was still gently tracing the left side of Sara's face.

"Either tell us what happened, or get a room," Mick said, from far too close.

"You know those Christmas movies where an angel shows you your future?" Sara asked.

"Um, yeah?" Jax replied, looking just a bit perplexed.

"It was exactly not like that," Snart concluded.
