"Hey. Bout time you got back," he said, by way of greeting.
Oliver smiled, and glanced down at Felicity. "We had to check on William."
"Of course you did. My advice? Don't let him grow up. Wish I coulda done that. Keep 'em small and safe forever. Sara was just here."
"Good," Oliver said. "I'm sure she needed to see you, after this last mission."
Felicity laid a hand on Quentin's arm. "She knows that it wasn't really you…that you'd never…do…that…" Her voice trailed off at the blank look on Quentin's face. "Oh, crap," she muttered.
Quentin looked from Oliver to Felicity and back again. "I'd never do what? What the hell happened? Sara kept insisting that she was fine."
Oliver sucked in a deep breath, and spoke as calmly as he could. "That news footage from Central City?"
"Yeah? Looked like some kinda Nazis or something."
"Yes. They came from another earth. You understand that most of us have doppelgangers on these other earths…and I think you know better than most of us, those doppelgangers aren't always like us."
"Yeah…"
"The you on Earth-X was a very bad man."
"And Sara?" Quentin demanded, with a sinking feeling.
"We don't know much about her, other than…" Oliver's voice trailed off at the horrified realization dawning in Quentin's eyes.
"No."
Felicity stepped in close again. "It wasn't you. We know that. Sara knows it, too."
"Why didn't she say anything?"
"Because, Quentin, Sara loves you, more than anything," Oliver said gravely. "She didn't want you to think that there could ever be any version of you that could hurt her."
"Sorry!" Felicity squeaked.
Quentin looked up at Oliver. "I hope you took care of the bastard."
"We did."
"Good. What about the two of you? What were you on this other earth?"
Felicity smirked. "Oh, him? He was evil incarnate."
Quentin snorted. "And you?"
Oliver smiled fondly at his bride. "Felicity got herself in trouble for sharing food with starving children."
"Yeah, that sounds about right." He sighed, and scrubbed a hand over his face. "My baby girl…"
Oliver laid a firm hand on Quentin's shoulder. "It wasn't you, and it wasn't her. Try not to dwell on it."
"How's that work for you?"
There was no good answer for that.
