D.E.O. Headquarters

"So...you're from the same Earth as The Flash?" Asked Winn, curiously. Sara nodded. Having convinced Kara to at least hear her out, the Kryptonian had promptly dragged her ass back to the DEO and ordered her to explain. Now, the assassin was sat in, what she assumed, was a briefing room with an all-too-curious tech guy, a stoic-faced man and an extremely sceptical looking Kara. "And your boss wants you to stop Supergirl saving Alex, or we're all dead?" Sara nodded again, though she couldn't quite tune out Kara's scoff from the corner.

"C'mon Winn," the hero groaned, clearly not buying Sara's story, "She's obviously just trying to keep me away from Alex! I mean seriously, I couldn't destroy Earth, it's my home!" Sara groaned and slammed her head onto the table.

"That's what I've been saying! This whole thing is a trap, they WANT you to storm in and try to save your sister so they can infect you with that red...whatever-the-Hell you call it..."

"Kryptonite." Came the resounding reply, causing the assassin to roll her eyes.

"But it doesn't work out like that, right?" Sara looked at Winn, then to Kara and back again with a sigh.

"No. In the future Rip showed me, Kara went insane and destroyed the complex, then your Earth."

"You said I'd be responsible for Alex's death. You can't keep me here Miss Lance, so let me go and save my sister!" Snapped Kara, taking a step towards Sara. Sara stood, her frustration at the annoyingly adorable, if completely unreasonable and stubborn alien, finally boiling over.

"You are responsible, Miss Danvers," She seethed, her voice a deadly calm that made even J'onn shiver, "The complex collapses and Alex is crushed. YOU kill her. And the grief and the red stuff drive you mad. You destroy your Earth and become a threat to every other one, including mine." Kara's face fell with every word that left Sara's mouth, the fight visibly melting out of her and Sara immediately felt terrible.

Kara's face fell with every word that left Sara's mouth, the fight visibly melting out of her as she lowered herself into a chair. For a moment, she couldn't help but see herself in Kara's eyes. If she had the chance to save Laurel and someone was telling she couldn't...actually, they already had done that and it felt horrible. Sara sighed and ran a hand through her hair.

"Look," She began, her voice much more relaxed, "I know exactly how you feel. Really, I get it," She said, as she moved to sit next to Kara, "And like you said, I can't stop you from doing anything. Bu if you go, your Earth will die by your hand."
