Summary
Self-awareness and control were among Lex Luthor's many strong suits, and he knew that allowing himself to sink into obsession yielded great results.
But what he couldn't understand was why his focus was being torn between taking down Superman, an alien threat, and coveting the attention of Clark Kent, a Midwestern journalist.
Or why his fixation on Clark was threatening to consume him whole.

Summary
The Wayne family was predominantly successful in many ways; being strong, healthy, and all absolutely handsome from a supposedly upstanding background with no means for mistakes, weakness, or forgiveness. “Having flaws or petty arguments puts a target on your back. Fix it, keep quiet, or die,” said their very blunt but importantly, hypocritical father. So, masks stayed on, even within the Wayne Manor.
To the protégé’s in the Wayne family— the Kryptonian, Man of Steel, Boy-Scout, Big Blue, or simply ‘Supes’ was known an associate of the Justice League that their father tolerated. Little do they know it is all complicated than that behind closed doors with Bruce’s relationship with the strongest man on earth. Yet, two fights occur, and someone died. In the end, will love fix all?
Easy intro: After a rough introduction and even failing mending relationship between World’s Finest, a member of the Wayne family passes away. Clark Kent, now having a wavering heart of gold, feels a inclination to help hand to the family despite the never-ending rocky road relationship between him and with the Dark Knight, also known as Bruce Wayne, the playboy multi-billionaire, AKA his miscommunicated ex-fling once upon a time.

Summary
Lena Luthor has been at the center of several assassination attempts, orchestrated by her now imprisoned brother, and all of which have been thwarted by the DEO and Supergirl.
But Lena is getting more and more frustrated by the secrets the DEO (and Supergirl by extension) is keeping from her. She vents her frustration to Kara, who against her better judgement agrees to go with Lena on a non DEO sanctioned outing to one of Lex’s abandoned buildings. There they discover a secret lab, which becomes their prison when they fall victim to a trap Lex has set for Lena and Supergirl, in the form of red kryptonite.
Lena’s not worried, because for the first time in weeks she’s finally dodged her super hero shadow. It’s just her and Kara, so of course the red k shouldn’t have any effect on them.
She’s not worried, until she sees the look of absolute panic in her friends eyes.

Summary
Lena walked over to her scotch tray and poured herself a glass. She felt a cold gust of wind hit her back.
“You know I’ve always had this fantasy… of you just like that… pouring me a glass of scotch…”
Lena froze. She knew that voice all too well.
“Be a good girl and bring me a drink, Lena. I’m parched.”
Lena turned around to find Kara, sitting on her white leather couch, wearing her usual slacks and a button up shirt, smirking in a way she’d never seen the blonde smirk before. Kara’s eyes were dark as night, but they had a certain glow about them, illuminated by the moon peaking through the glass walls of the office. “K-Kara,” Lena stuttered.
“Are you done being angry with me, Lena?”

Summary
"Why did you come to me? You've got no reason to trust me."
"I don't. I just didn't have any other options. You weren't afraid of me. Please," Superman gasped. "Someone needs to stop me."
He turned his head aside and scorched a ragged line over the concrete, several feet away from where Bruce stood.

Summary
Since moving to National City three weeks ago, Lena’s been working non-stop. She desperately needs some stress relief, and a club’s masquerade night sounds like the perfect solution.
Kara has no plans for a one-night stand, but she can't resist the rare chance at anonymity...especially when she’s so drawn to the woman hitting on her.
(Kara and Lena first meet under much different circumstances. They try to turn a one-night stand into something more, contending with trust issues and emotional hurdles along the way.)

Summary
Lena realized, with mounting horror, that it wasn't Lex's portal watch; she'd had that in her pocket. That was-
Mercy's lackey flipped the cover open, and just as Lena blurted out a sharp "Don't," he pushed the button.
"You idiot," Lena choked out. "That's my signal watch."
"Signal watch?" said the Child of Liberty.
"Signal watch?" said Mercy. "Signal watch! You idiot," She rounded on the others. "We need to leave, now. Get Luthor and-"
Somewhere in the distance, there was a crash of shattering concrete and a series of harsh bursts of automatic gunfire. Mercy tensed, taking a step from the door as the sounds grew closer. Cracking concrete. Rending metal. Screaming.
"You have no idea what you've done," Lena choked out.
"What do you mean?"
"The Kryptonite in your chest," said Lena. "It's red."***
After Lena betrays Kara and abandons her at the Fortress of Solitude, Kara is again exposed to radiation from Red Kryptonite, unleashing her darkest thoughts and impulses. Will Kara and Lena burn the world together, or rise from the ashes?

Summary
Heroes have a higher moral fiber that puts them above the villains they fight. Heroes have the moral strength and self discipline to rise above the violence, to have the most peaceful solution; to have the glory, and the crowd's favor.
Accomplishing what her darling brother was never able to do, Lena Luthor perfected the 'hero' the world needed. A 'hero' that was indestructible, obedient and unafraid to do what many other of Earth's so called superhero's would not do. Crossing that fine line between justice and justice...Kara Zor-El, the last daughter of Krypton...is a new breed of superhero.
To some, Supergirl is Earth's mightiest protector...and to others, she's the symbol of the beginning of the end.
