"Ow! Ow! Ow ow ow!" Kara winced as her sister continued dressing the wound at the DEO. "That stings."

"Baby. That sword cut pretty deep," Alex stated in a concerned tone "How is that possible?"

"I don't know. His sword must be made of some pretty strong alien tech," Kara hissed "J'Jonn, is he awake yet?"

"Still unconscious," the Martian Manhunter confirmed "but when he wakes up, I'll be sure to let you know. Agent Schott, any luck getting an ID on our mystery man?"

"I have checked every local, federal, international, and intergalactic database known to man and I got nothing," Winn sighed "I mean, this guy's a ghost."

"Ghosts aren't real," Kara groaned as she stood up.

"Where are you going?" Alex questioned.

"Back to L-Corp," Kara responded as she struggled to fully rotate her arm "Lena was attacked for a reason, and we need to find out why."

"Kara, you can barely move your arm."

"You didn't see the look on Lena's face, Alex," Kara told her "she was terrified. I have only ever seen one person that scared before. Me. When I looked back in my pod and watched as Krypton was destroyed. The only thing that made that fear go away was when I came to live with you. Somebody has to the same for Lena," Kara stated "and that someone is going to be me."


Lena sat alone in her office, slowly drinking a fresh cup of tea with trembling hands, when a gust of wind caused her to jump.

"Sorry," Supergirl apologized "I didn't mean to scare you."

Lena nodded silently as she nervously wrung her hands together "How's your arm?"

"Little stiff, but I'll manage," Supergirl assured her "Miss Luthor, I was wondering if I could talk you about the attack earlier today? Do you know who it was who attacked you?"

Lena paused, a heart-stopping chill running down her spine as she remembered horrors that were all too familiar. "His name is Emrys," she managed "And he is a monster."

"Is he after you because of something your brother or your mother did?"

"Emrys doesn't care about the Luthors," Lena disputed "All he cares about is seeing me dead. He's hunted me for years; ever since I was a child. When I went to live with the Luthors, I convinced myself that he wasn't real. But now he's back," Lena's voice trembled "He's going to kill me."

"No he's isn't," Supergirl insisted "Emrys is in custody. He won't be able to hurt you or anyone else ever again."

"You don't know that. Whatever hole you put him in, it won't be deep enough," Lena insisted "no matter where I'll go, he'll find me. He always finds me. I'll never be safe. Ever."

"Miss Luthor."

"You saw what he did today! He tossed grown men and women around like ragdolls. He set fires with a look. He brought you to your knees with one swipe with a sword! There is nothing on this earth that can stop him!"

"Lena," Supergirl spoke in most comforting of tones "I promise you, Emrys will never hurt you again."

As Supergirl left, Lena sat to finish her tea, only for the cup to suddenly shatter as her eyes turned gold. Lena gasped as she jumped back, her heart racing as her body swelled with terror. Desperate for a sense of peace, she ran to her desk and pulled out her pills and popped another into her mouth, grateful as she felt the drugs quickly start to take effect.


"Any luck?" Alex asked as her sister flew in.

"Not really," Kara sighed "Lena's still pretty shook up but I did manage to get a name for our mystery man. Winn, can you run Emrys through the database and see what you can find?"

"I am on it."

"Glad you're back, Supergirl," J'John greeted. "Our new friend just woke up."


Kara walked downstairs to the containment units, where the strange man sat patiently in his cell.

"Where am I?" he asked.

"Somewhere you can't hurt anyone else."

"I am not your enemy."

"Could've fooled me," Kara disputed "You broke into an office building, hurt dozens of people, tried to kill someone, stabbed me with a sword. You guys have a very interesting way of saying hello on your planet, Emrys."

"Emrys," the man smiled "now that is a name I have not heard in a long time. I suppose Morgana told it to you?"

"Morgana?" Kara repeated.

"The woman you call Lena Luthor. Heed my words, Supergirl. That woman is darkness incarnate."

"Because she's a Luthor?"

"Because she is a monster. One who takes pleasure in the torture of innocents," the man declared rising from his seat "I have watched her take men of honor and twist them to her will. She has slaughtered kings and destroyed kingdoms. And now she has brought her wickedness here. And I am the only one who can stop her."

Kara stared at the man for a moment, his eyes filled with pain and conviction. He really believed Lena was a monster. "Who are you?"

"I am the sole survivor of her reign of terror; from a land of myth and time of magic. My name," he revealed "is Merlin."
