"Are you alright, Kara?" Barry asked as Kara sat down. Clearly, she was not still back in full shape and still traumatized from the experiments but she seemed to be healing at least.

"I'm good, Barry. Really. Don't worry." Kara said, her hands shaking, which worried him.

"Kara… you know I'm here for you, do you?" Barry said before they saw J'onn passing by as Barry turned to him, noticing how disturbed he was. "J'onn. Is everything alright?"

J'onn sighed. "It's… something personal happened."

"Can we help?" Barry asked and J'onn took a breath.

"I… I'll let you know if I need something."

"If there's something you need to talk about—"

"Barry, I appreciate your concern but Kara needs your help more than I do." J'onn said and Barry nodded before J'onn left.

"I asked Nia to use her dream-walking powers to help me remember." J'onn told Clark as he sighed. "I have a brother. He wasn't born evil. He had… a problem. And my people ostracized him. For that he betrayed our kind, started a war with the White Martians. And…" He looked down in shame. "We sentenced him to the Phantom Zone. Father didn't take it well and he was so consumed with grief… and to spare him of that pain, I erased Malefic from our minds. In my culture, a Martian wiping the mind of another Martian is the greatest sin there is. I've spent years trying to repent for fleeing Mars…"

"You've done more than enough to make up for your sins. You can't blame yourself. You had your reasons. All you did, was that you proved that you loved your family and you did what you could to protect them." Clark assured as he held J'onn by his shoulder.

"I erased my brother from our memories. I may as well murdered him." J'onn said guiltily.

"Now you remember. Now you might make up for it." Clark said.

"What makes you think I can help him?" J'onn questioned.

"I… don't know. I'm not saying he can be saved. I'm saying that you have a chance to do things differently." Clark advised.

Winn, Cisco and Curtis were in the lab before a technician entered.

"Hayes. Can we help you?" Curtis asked.

'Hayes's eyes glowed green. "I want you to build something for me."

J'onn entered Kara's room as Barry was sitting next to her with Caitlin.

"How are you doing, Kara?" J'onn asked.

"I'm… I'm fine. Really." Kara said weakly but it was obvious to them that she was still healing.

"Have you found Lex?" Barry asked as he turned to J'onn.

J'onn paused, considering if he should tell them but was worried that they would do something reckless. "We're working on it. We have a lead. I think you should stay here. For now." He said cryptically.

Later

Batman, Superman, J'onn and Wonder Woman scoured the building.

"This place has just been cleared. I think we're too late." Batman said.

"Actually… you're right on time."

They were surprised to see Winn, Cisco and Curtis.

"What are you doing here? How did you get here?" Batman demanded.

Suddenly, the trio of scientists picked some device and fired as the blast knocked Batman and Wonder Woman down on the ground and J'onn immediately realized what was going on.

"Malefic. Let them go!" J'onn ordered and Winn, Cisco and Curtis aimed at him as he groaned, when the beam hit him and he reached out. "I know you can hear me, brother! I'm sorry I banished you! I'm sorry I left you in the oblivion!" He pleaded. "If you want to punish me, you have every right to but let them go! This is between you and me! They don't deserve to be punished for my sins! Please! I'm begging you! Let them go and face me, brother!"

Suddenly, Winn, Cisco and Curtis came to, dropping the weapon as they gasped.

"What the hell…" Winn whispered.

"What's going on? How did we get here?" Curtis wondered, all of them confused as they looked around.

"It's complicated. You need to get out of here before—" Suddenly, J'onn groaned, holding his head as he was attacked psychically, when Malefic appeared out of nowhere.

"On Mars, you had nothing but cruelty for me. Now you're being sentimental?" Malefic taunted.

"They're my family." J'onn said as he turned to face his brother.

"Family is supposed to destroy you! You taught me that, when you erased me and banished me into the purgatory for 300 years! 300 years in oblivion! You took everything away from me!" Malefic snarled.

"I know what I did. This is between you and me, brother. Your anger should be for me, not my friends." J'onn said.

"So be it." Malefic said as he and J'onn flew up.

"Shouldn't we—"

"No." Batman stopped Cisco. "This is J'onn's fight now."

J'onn and Malefic were in the air, exchanging blows before Malefic grabbed him.

"Where has all this love and regret come from?" Malefic demanded.

"It's called humanity. Something you should learn." J'onn said, slamming Malefic to the wall of one of the buildings as it cracked. "I do not wish to fight you but I will stop you from hurting my friends."

"All I'm doing, is paying you back for letting me rot in the Phantom Zone!" Malefic snarled.

Malefic headbutted J'onn and hit him in the chin with an uppercut as J'onn was sent flying back. Malefic flew at J'onn as they crashed through a window into an office area of a building and people screamed and ran in panic. They exchanged blows but J'onn was quickly overpowered due to his restraint as Malefic grabbed him and slammed him to the ground before he punched J'onn repeatedly but then, Malefic stopped upon noticing that J'onn wasn't fighting back.

"Why aren't you fighting back?" Malefic demanded.

"I'm sorry. I'm so sorry." J'onn said weakly. "We should've helped you. Tried to reach you. But I made a terrible mistake. If you'll find peace by killing me… do it."

Malefic contemplated, glaring before he got up. "No. I will not kill you. Death would be too easy. There was a time, when Fa'ra'too'rik would forbid me from killing you. But I have no strings on me anymore. I sentence you to learn what it feels like to be abandoned and forgotten in a purgatory… just like me. When I'm done, you will wish I had killed you tonight. I will show you how everyone around you will suffer for what you did. Farewell, brother."

Malefic teleported himself as J'onn stared, to beaten up to do anything.

Later, A.R.G.U.S.

"He let you live? Why?" Lyla asked.

"Why does your brother hate you so much?" Barry asked.

"It's complicated." J'onn said. "He betrayed my people and he blames me for leaving him to rot in the Phantom Zone."

"How are we going to stop someone, who has psychic powers?" Winn asked.

"I think that as a safe precaution, we should all wear psychic inhibitors." J'onn suggested.

"Good idea." Cisco said. "Winn and I will get to mass-producing them."

"J'onn, how are we going to stop your brother?" Clark asked. "He escaped from the Phantom Zone once. What are our other options?"

"I can't kill him." J'onn said. "Even if I wanted to, H'ronmeer's curse will not let a Martian fight his brother."

"Maybe we can strip him of his psychic powers somehow." Winn suggested.

"J'onn, I think that Harry, Alex and Caitlin should do a brain scan on you." Clark said. "Analyze your powers and…"

"…find a way to negate Malefic's abilities. Good thinking." J'onn nodded.
