Lena stared at her adoptive mother, fingers curling into fists. "So, I really am a Luthor." Truthfully, that was the less alarming part of the truth. The more alarming part was how her mother had dropped this bomb when she was in jail — proving that she could still manipulate Lena despite being not in a position of power. And, of course, what being biologically a Luthor meant.

"We're the only two Luthors left. And we need to be there for each other," Lillian's chains rattled as she reached across the table to touch her daughter.

"No." Lena pulled her hands away and stood up. "How could you have let this happen?"

"Lena, darling, I don't know what you're saying…"

"You don't get to call me that when I was a human game of chess in that household," Lena stood up and backed away from her mother. "Sure, I was plenty interesting. But just as entertainment, and as practice for the future or the better child. Never as a person."

"Lionel, you were his favorite child," Lillian pleaded with Lena. "And Lex, he loved you."

Lena rolled her eyes and walked to the door of the cell. "If you still truly think that, you don't deserve to know what Lex's love was really like."

Kara walked into Lena's office at L-Corp and nearly dropped her bag of bagels. Lena was curled up on the couch in front of her chess board, shaking and crying.

Kara had seen Lena's more vulnerable side before, when they were in her apartment, but never at L-Corp. It seemed like there were two sides to Lena — the tough side and the side Kara saw. Of course, Kara understood why that was the case, so she didn't begrudge Lena for it.

"Lena, honey, what happened?" The pet name slipped out without Kara really intending it to. She wanted Lena to know she was loved right now.

Lena looked up at Kara's eyes, and then at the bagels. "My mother."

Kara bit her lip and sat the bagels down on the table, pushing the chess board to the side. "What happened? She's still safe in jail, right?"

"I don't really think anywhere is safe from my mother, even if she's in jail. There are still all the fanatic followers of CADMUS," Lena sighed. "But yes. She is. Yet, she somehow found a way to hurt me while in a jail cell."

Kara handed Lena a cinnamon-sugar bagel, Lena's favorite kind. "Do you want to talk about it?"

"She didn't even mean to," Lena shook her head, choking back tears. "But I learned today that I wasn't adopted into the Luthors. Lex's — our father had an affair with my mother. Lionel just brought me home because my mother couldn't keep me."

Kara absentmindedly pet Lena's hair while she ate the bagel. After a few minutes, she put it down and turned to face Kara.

"I don't know. I guess… before, I could tell myself that of course it was horrible, but it wasn't really incest. He wasn't really my brother, because we didn't share blood. And at least that way, it hurt less and made me feel less evil."

"Lee, you're not the wicked one," Kara stroked Lena's hand. "You never did anything wrong,"

"I wanted approval. Acceptance into the Luthor family. I did things — " Lena got choked up, and Kara transitioned to rubbing her back. She had to be careful not to break anything.

"Things that anyone would have done. Well, anyone who had an adopted brother eyeing her like that. It was all him, Lee. It was nothing to do with you," Kara muttered.

"Nothing to do with me," Lena repeated, leaning on Kara's shoulder. Thankfully, the position wasn't too uncomfortable, even when Lena fell asleep from the crying and stress of the day.

What are we going to do? Kara thought as she ate a raisin bagel. A quote from a show she'd watched the first episode on Netflix the other day occurred to her. "Knowing it's real means you've got to make a decision. One, keep denying it. Or two… do something about it."

Lex Luthor was behind bars, so there wasn't much more Kara could do about him. What she could do, however, was defeat CADMUS. Because now it was even more personal than ever.
