Felicity should have been surprised to find a partially drunk assassin on her couch, but 4 years with Team Arrow had made her immune to things that most people would find disturbing. So instead of freaking out she just sighed and asked:

"Shouldn't you and Doc Brown be going back to the future?"

Sara chuckled and took a swig of vodka. "Yeah, except this visitor from the future came and told us we're all going to die. He and Rip are locked in the wave rider comparing notes "

She refused to look at Felicity as she sat next to her, only wordlessly handed her the vodka bottle.

They sat there for a couple minutes, passing the bottle back and forth. "I heard you and Ollie broke up." Sara commented.

"Yeah." Felicity said softly.

"And that he has a kid." Sara said.

Felicity opened her mouth, but no sound came out so she just nodded. The weight of Oliver's secret was still weighing on her.

"Dumbass." Sara muttered.

Felicity let out a humorless laugh.

"I'm serious." Sara said. "He had a chance. He had..." She shook her head. "If it had been me, I'd have told you straight away."

"That you'd fathered a secret child?" Felicity said. They looked at each other and cracked up.

"You know what I mean." Sara said.

Silence again.

"How was...the funeral?" Sara asked, her voice hushed.

Felicity closed her eyes. "It was...beautiful. She would have loved it."

Sara nodded. Her shoulders shook and as Felicity watched, she pressed her hand to her mouth.

"Sara."

"It's not fair." Sara said. "I'm a time traveling assassin. Time travel, Felicity and...and I still couldn't save my own sister." She leaned forward, trying to hide her tears. Feliity put her hand on her shoulder.

"I know." She said, giving her shoulder a squeeze

"And Ollie killed Dahrk?" She asked. Felicity nodded. "Good." Sara said.

"It's not your fault." Felicity said. "There's nothing you could have done."

"Out of everyone, I was the only one who could have done something." Sara murmured. Felicity slid her hand into Sara's and squeezed. "Um.." Sara cleared her throat. "Can I stay here? At least until the Wave rider ships out again. I don't think I want to stay with my dad and...I don't want to be alone."

"Stay as long as you want." Felicity replied. "And now, I'm cutting you off." She said, grabbing the bottle. Sara pouted, but let her take it.

"Only because I want you to." She said. "Otherwise I would have taken you down. I'm a badass assassin, you know."

"Of course." Felicity said, shaking her head as she walked to the kitchen. Putting away the bottle, she turned to look at Sara. She was staring, blankly out the window, her mind a hundred miles away.

"I met this nurse in 1958." She said. "She was lesbian, but she was scared; it being the 50's." She paused. "I wonder what happened to her."

"I can look." Felicity offered. "Just give me her name and -"

"No." Sara said. "Some things are best left in the past. I...I like the idea of her meeting someone she could love honestly and lived happily with her." She looked over at Felicity. "I know that's probably not what happened."

Felicity came back and sat on the couch. "Trust you to have a star crossed time traveling romance."

Sara snorted. "It does sound like a bad fiction, doesn't it?" She admitted. "The blonde haired, lady assassin travels to the 50's to save the world and meets a beautiful, but shy and repressed nurse. They fall in love, but just before they can act on their passionate feelings, the assassin has to leave."

Felicity laughed. "You should write it."

Sara shifted nervously. "Does it have a happy ending?" She asked.

Felicity tilted her head. "For the assassin and the nurse?"

"No..." Sara said. "When the assassin comes back to her time, she realizes...that there's been someone there for her all along. She was just too broken to see it before."

Felicity bit her lip. "Oh?" She felt her face heating up.

"And..." Sara said. "She's not sure how to say it."

"I think she should try the direct approach." Felicity suggested. Sara looked at her intently. Felicity saw the second she shut down. The second she lost her resolve.

"Like I said: Bad fiction." She said, shaking her head and getting up to go to the guest room.

"Yes." Felicity watched her leave. "Bad fiction." She murmured.
