Night
"So let me get this straight," Oliver messaged his temples as he absorbed what Cisco was telling him, "You traveled twenty-three years into the future, met the last leg of the human resistance who fight against a robot army, created by Lex, and they told you that, in order to prevent that future, I can't fight something called The Amazo and that Lex has to die."
"It sounds crazy when you say it like that, but yeah." Cisco confirmed.
"Crazy? It sounds freaking insane." Diggle scoffed.
"Look, I know we're all tired but we have to be calm. We have to work together to prevent thing future from happening." Barry tried to calm them all.
"And how do you expect two groups who don't trust each other to work together?" Nyssa sneered.
"Did…I miss something?" Cisco asked confused as he looked around at everyone.
"They, um, know about Black Siren." Barry muttered.
"…Oh." Cisco said awkwardly.
"Yeah, oh." Roy said acidly.
"Look, it's been a long night, so why don't we all get some rest?" Joe suggested, trying to keep the peace.
"Maybe you're right," Oliver conceded as he turned to Diggle, Roy, and Sara, "Nyssa and I have been staying at a monastery about ten minutes. We have more than enough rooms if you want."
"We have some space here if you want." Caitlin offered.
"I think we'll take our chances." Sara said stiffly.
Monastery, next day
Morning
"So he's your kid?" Diggle asked Oliver as the two watched Sara and Nyssa play with Conner.
"Possibly. The timing adds up and there is a certain…resemblance," Oliver noted as he pulled a plastic bag with a blonde hair, "I need you to get this to Lyla, have her run a DNA test."
"Sure man," Diggle said as he took the bag, "man, I can't believe Laurel has a Doppelganger, an evil one at that. And Barry and the others chose not to tell us."
"I know," Oliver sighed, "I'm not sure how any of us are supposed to trust them again."

Same time
Barry was staring at the monitor, looking at the security feed for Black Siren's cell. Hearing someone approach him from behind, Barry looks back as Caitlin walked up to him.
"You okay?" Caitlin asked concerned.
"No," Barry sighed as he ran a hand over his face, "we really screwed up Cait. We should have told them about Black Siren."
"We probably should have," Caitlin admitted, "but what's done is done. What matters now is what we do moving forward."
"I'm not sure Oliver will ever trust us again," Barry admitted tiredly, "he doesn't trust lightly and we broke his trust. Even if we do get the others to trust us again, it won't matter because they'll know Oliver doesn't."
"So what are we gonna do?" Caitlin asked and Barry had no answer.
Monastery
Afternoon
"Okay, thanks Lyla," Oliver hung up his phone and paused, "you just going to stand there all day or what?"
"I didn't want to interrupt." Barry said as he stepped into view.
"What do you want Barry?" Oliver demanded as he turned to face the speedster.
"I'm sorry," Barry told him and Oliver looked at him curiously, "you're right; I should have told you about Black Siren. I know I broke your trust Oliver but what's happening is bigger than you and me. If we can't manage to work together, then we won't be able to stop what's coming."
"I'll put my personal issues aside and fight with you…but after that, I'm not sure I can ever trust you again." Oliver told him and Barry nodded.
"I understand. But you are my friend, which means more to me than you'll probably believe right now. But if you trust anything, trust that I'll have your back." Barry told him before speeding off, leaving Oliver to his thoughts.
