In National City, Kara flew around before she heard a bestial roar and flew into the mall to see a dragon-like creature terrorizing people, who were running in panic. Kara flew towards it and dodged, when it attempted to bite her and used her freeze breath to slow down the dinosaur. Kara attempted to punch the dragon but it broke through the ice and swung its head, sending her crashing to a wall. Kara punched the dragon in the face, knocking it out before it was reduced into a lizard as she trapped it on a makeshift cage.
Kara returned to DEO, giving Brainy the shapeshifter. "I'll make sure that the director knows about it."
"What do we got?" Kara stiffened as she turned around and heard the voice she had not heard in two years. "Is everything OK, Kara? You look like you just saw a ghost."
"Alex…" Kara breathed out, hugging her tightly. Deep down she knew it wasn't real but she couldn't hold back the tears as she sobbed.
"Hey, hey, it's OK. It's OK." Alex assured.
"Uh, we have a problem." Brainy called out.
"What?" Kara asked before she groaned, holding her head as she heard a high-pitch noise. In fact, it seemed that only she could hear it.
"Supergirl, what you're hearing is a high-frequency sound that can be registered only by a Kryptonian like you or your cousin."
Kara paled as she recognized the voice before turning to J'onn. "It's Henshaw."
"What? What are you talking about?" Alex asked.
"He's communicating with me through some high frequency that only I can hear." Kara said.
Brainy then turned on the screen and saw Henshaw and Cadmus operatives L-Corp laboratories and kidnapping Lena.
"Oh, no…" Kara paled.
"You and your sister have ruined my life. You and Alex Danvers are going to come to the abandoned warehouse at Waterfront Road in an hour, alone, or Miss Luthor dies." Henshaw threatened.
"He wants me and Alex. Alone. He sees anyone else, he's gonna kill Lena." Kara said.
"Kara, this is a trap, you can't—"
"It's Lena, I have to do something!" Kara snapped.
"I'll get my things." Alex went to gear up.
"No! It's too dangerous." Kara protested, holding Alex's hand, not wanting to lose her again.
"Kara's right, there's no way you're going there." J'onn said.
"J'onn, this isn't our first rodeo and hostage situation, besides, how many times have we stopped Henshaw before?" Alex argued.
"Alex, it's too risky." Kara said.
Alex glared at Kara. "We both risk our lives every day. Look, I can distract Henshaw and Kara can find a way to catch him off-guard and take him out."
"Either way, the longer we drag this out, the less time Miss Luthor has." Brainy said. "What are we gonna do?"
Kara sighed. "OK. But be careful. I'll watch your back."
Alex entered the abandoned warehouse, where she saw Lena in the middle of the warehouse, tied to a chair, with a bomb attached to it.
"Alex, no, it's a trap!" Lena protested.
"I know. Don't worry, Lena, it's gonna be OK." Alex then looked around. "Henshaw! I'm here! You wanted me here, here I am!"
"Where's Supergirl?" Henshaw demanded, holding a detonator.
"I'm right here." Kara said as Henshaw turned around, aiming his gun at her, holding in his hand the detonator. "Let Lena go. This is between only you and us."
Henshaw smirked. "You can't take me out, even if you wanted. I've planted power dampeners around this place. I was ready for you, Kara."
"I don't need my powers to stop you." Kara sneered.
Henshaw was about to press the trigger but Kara tackled him before he could as they struggled for a moment. Alex approached Lena as she tried to free her but in the struggle, Henshaw dropped the detonator as the trigger hit the ground and an explosion followed.
Next thing Kara knew, she was flying in the air and again she heard a dinosaur roaring in the distance as she felt a strange sense of Déjà vu. Kara flew into the mall again to stop the shapeshifting alien and cage it as she flew into the DEO again.
"I'll make sure that the director knows about it." Brainy said again and Kara stared. What was going on?
"What do we got?" Alex asked and Kara stared at her in horror. "Is everything OK, Kara? You look like you just saw a ghost."
"What…" Kara breathed out, wondering what was going on. "What the…"
"Hey, hey, it's OK. It's OK." Alex assured, holding Kara's shoulders again.
"Uh, we have a problem." Brainy said and Kara then realized that she was reliving the same day again before she again heard the high-pitch noise with Henshaw transmitting a message to her.
"Supergirl, what you're hearing is a high-frequency sound that can be registered only by a Kryptonian like you or your cousin."
"Kara, are you OK?" Alex asked as she held Kara gently.
"Henshaw…" Kara breathed out. "He has Lena. He's sending me a message."
Brainy turned on the screen and saw the footage of Henshaw kidnapping Lena.
"You and your sister have ruined my life. You and Alex Danvers are going to come to the abandoned warehouse at Waterfront Road in an hour, alone, or Miss Luthor dies." Henshaw said.
"We need to do something—" J'onn started.
"No!" Kara protested. "He wants me and Alex, or Lena dies."
"Kara, this is a trap, you can't—"
"I'm not gonna just stand by, while Lena's life's at risk!" Kara protested.
"I'll get my things." Alex said, going for her gear.
"No!" Kara protested again as she held Alex by her shoulder.
"Kara's right, there's no way you're going there." J'onn said.
"J'onn, this isn't our first rodeo and hostage situation, besides, how many times have we stopped Henshaw before?" Alex argued.
"Alex, you can't go there, please…" Kara begged.
Alex glared at Kara. "We both risk our lives every day. Look, I can distract Henshaw and Kara can find a way to catch him off-guard and take him out."
"Either way, the longer we drag this out, the less time Miss Luthor has." Brainy said. "What are we gonna do?"
Kara groaned. There was no way she could talk Alex out of it in time. "We need to be careful."
Kara entered the warehouse with Alex, as they saw Lena restrained to a chair, with the bomb attached to the seat.
"Kara, Alex, no, it's a trap!" Lena exclaimed.
"Lena, don't worry." Kara assured as she looked around. "Henshaw! Show yourself!"
Henshaw laughed as he stepped up from the shadows. "I have you right where I wanted."
"Let her go." Kara raised her hands. "This is between you and us. Lena has nothing to do with this."
"She has as much to do with it as you two." Henshaw sneered. "It's her weakness that forced Lilian to such drastic measures!"
"She's an innocent." Alex said. "You want to punish us for what we did to you? Fine. But let Lena go."
"I'll settle for dragging you both to hell with me." Henshaw was about to pull the trigger.
"No!" Kara rushed at him as they struggled for the trigger before she punched him and he dropped the trigger but Kara caught it before it would hit the ground. Kara threw it away as they resumed their fight, exchanging blows before Henshaw pinned Kara to a pillar and grabbed her by her throat, choking her as Kara gasped for air before Lena hit him in the head with a piece of pipe.
"You alright?" Lena asked.
Kara nodded, taking deep breaths as she glanced at Henshaw's unconscious form. "Let's just get out of here and call J'onn."
They went outside before they saw a shimmer of red light and turned to see a red spot suddenly appear on Alex's chest as Kara and Lena widened their eyes in horror and Alex paled.
"No!" Kara cried out but before she could react, a gunshot rang out and blood soaked through Alex's shirt as she fell down.
Kara woke up, reliving the day as she ended up in the air again and once again, she took down the alien shapeshifter in the mall and returned to the DEO. She tried everything to save Alex.
Get ahead and save Lena before Henshaw would send the message? A little while later, it turned out that Henshaw had planted a bomb inside Lena that exploded, when Alex was debriefing her.
J'onn shapeshifting and disguising himself as Alex? Didn't help, Alex later arrived with a backup but was caught in a crossfire between DEO and Cadmus's operatives, with Kara powerless to save her.
Kara then flew onto the rooftop of DEO, curling to a ball, sobbing before Eddie approached as Kara glared at him. "Why are you punishing me like this?"
"I'm not punishing you. This is a lesson you need to learn." Eddie said. "You understand it, you'll get your piece of the Life Equation and you'll be free of this time loop."
"What lesson?" Kara asked. "What lesson?! I'm in no mood for these games?!" She attempted to throw a punch at Eddie but he teleported himself.
Kara returned to the DEO but instead of greeting her friends, she rushed into a corridor, leaning onto a wall, unable to hold back her tears as she was on verge of ripping her hair off. Why was she forced to watch her sister die, over and over again?
"Hey." Alex knelt towards Kara, holding her by her shoulder, confused at why was Kara so devastated. "What's going on, Kara?"
Kara panted out, not sure if Alex would believe her as she held Alex's hand. "I just… I just can't stand the thought of losing you. Watching you die, over… and over again…" She sobbed.
"Hey, hey, hey. It's OK." Alex held Kara's hand gently. "You're not gonna lose me, Kara."
"I am. I already have." Kara sniffed.
"Hey, hey." Alex held Kara by her shoulders. "We've been together through thick and thin, and no matter what, we'd always pull through."
"It won't be like that forever. I'm gonna lose you eventually, no matter how hard I'll try to save you." Kara breathed out.
"You can't blame yourself for that, if that happens." Alex assured. "Powers or not, just because you're an alien, it doesn't make you any less human than us." She smiled. "Look, as an agent, I've learned to accept long time ago that I may not be able to save people I care about, no matter how many innocent people I may rescue. I've lost my share of friends and people I considered family too. That doesn't mean that I can't stop trying to save them. But you need to accept that the people you love, are gone. But as long as you carry them in your heart, you're not gonna lose them forever."
Kara stared before nodding as she heard Henshaw's message again.
Kara and Alex came into the abandoned warehouse as they faced Henshaw again.
"Save Lena. I'll handle him." Kara ordered.
Kara rushed at Henshaw, trying to disarm him of the trigger, while Alex approached Lena, disarming the bomb and undoing her restraints. Kara and Henshaw exchanged blows briefly and even without her powers, Kara was still formidable in hand-to-hand combat. Kara managed to block Henshaw's punches before she punched him in the chest and grabbed his arm before she grabbed him in neck lock.
"It's over." Kara sneered as Henshaw was struggling for breath. Henshaw saw Alex and Lena run and pulled out his gun and fired as Alex fell down and Kara widened her eyes. "No!"
Kara glared at Henshaw with rage before snapping his neck and rushed to Alex as she and Lena knelt down, holding Alex's wound as Alex breathed out, paling from losing blood quickly. "Alex, hold on. Alex…"
"I'm not sure I'm gonna hold out for long, Kara…" Alex whispered.
"Just stay with us, OK?" Lena said.
"Kara…" Alex held Kara's hand gently as tears trickled down the cheeks of both girls. "It's alright…"
"I'm sorry…" Kara sobbed. "I'm sorry I couldn't save you. I failed you… I failed you, Alex…"
"You could never fail me…" Alex assured, smiling.
"I don't know how can I do this without you…" Kara sniffed.
"You can. Because you're the strongest woman I know." Alex said. "Not because of your powers, but because you're as much human as I am." She caressed Kara's cheek gently. "Don't blame yourself, OK? It's alright."
Kara nodded, accepting that there might be nothing she can do to save her sister. "I love you, Alex."
Alex smiled. "I love you too, Kara."
And with that, Alex tilted her head as Kara broke down, sobbing into Alex's chest before she faded in a glow of light.
Well, this one was a bit tricky.
Hope this worked, this was inspired by Arrow 8x06, where Oliver and E-2 Laurel were trapped in a time loop, where Quentin kept dying and Supergirl 5x16, where * ! Warning: spoiler for those who have not seen Supergirl Season 5 ! * Alex ended up going into VR to avoid the grief, once she and Kara learn that in Post-Crisis timeline Jeremiah died and Alex ended up playing Supergirl, which was kind of hilarious, at least to me. * end spoilers * But, given that this isn't Miss Self-Righteous Cheerleader, hope you liked how I did Kara's test, which was accepting that no matter how powerful she is, she can't save everyone and sooner or later, she'd lose people she cares about, no matter her powers.
And Henshaw was a human here, not Cyborg Superman, if you're wondering how did Kara overpower him.
Now, Constantine's next and I think I know what am I gonna put him through but still not sure what should I do with Clark. Asides from his fallout with Lex and them becoming mortal enemies, what would be Clark's greatest failure here? Anything from the films and Smallville I can get behind, otherwise I'm just going to improvise and do something rather short before heading to the climax of the story.
So, what do you guys think about it?
