A/N1: Happy 10 Year Anniversary to me! This is gonna be a tear jerker, just a warning. I got the title from the song of the same name by Shania Twain.

Kara Danvers was sitting on her couch, watching the new season of Puss in Boots, when she heard Alex screaming her name. Her heart jumped to her throat and she was flying above National City in less than three seconds. She flew in the direction of her sister's scream, scanning every building along the way. She left the city behind and was well into the desert when she spotted Alex. She touched down next to her sister and rushed to her side.

"Alex, I'm here! Where is everyone?!" Kara asks as she scans the area, "Alex?"

Kara scanned her sister as she knelt in puddle of Alex's blood. Her right leg had broken, ripping through her femoral artery. Kara pulled Alex's belt free of her pants and tied a tourniquet midway down her thigh. "I've got you, you're gonna be fine…" Kara told her sister as she heard Alex's heartbeat get fainter and fainter. She took off, speeding towards the DEO.

"Alex! Nononononono… I'll save you! We're so close to the bunker! Please Alex…" Kara sobbed as she heard her sister's heart stop. She landed at the DEO bunker, cradling her sister's body, not a moment later. She sped through the cave and scared the doctors when she lay Alex down on the table. "Help her…"

The doctors immediately sprung into action, "There's no pulse! Get the cart!" One of the nurses came running in, rolling a crash cart forward. Kara watched as they ripped off her kevlar and sliced open her shirt. She watched as they charged the defibrillator and she watched as her sister's body left the table only to slump back down, lifeless. She watched as the doctors charged up the paddles and she watched as her sister didn't regain a pulse. The doctors tried three more times before Kara saw their shoulders slouch as they drew into themselves. One of the doctors turned to Supergirl and said, "I'm sorry…"

"Don't give up! She's not dead!"

"Supergirl, even if we could get her heart restarted, she's lost a lot of blood… I'm sorry, but there's nothing we can do…"

"There's always something you can do!" Kara advances on the doctors.

"Supergirl! Stop!" Hank commanded as he entered the hospital wing. He saw Alex's body and tried to mask his shock before turning back to one of the women he considered a daughter, "We were raiding a warehouse in the port district when the Kalvar we were hunting grabbed Alex. I was here, I couldn't get to her fast enough… She fought with it in the air before it dropped her,"

"You should have called me! I should've been there! Her blood is on your hands!" Kara yells at Hank, blasting him with her heat vision. He flew backwards through two labs and another wall before stopping. As he got to his feet, Kara hits him with an uppercut before flying above him and punching him back to the ground. She punches him through three floors before she stops at the sight of blood at the corner of his mouth.

"Kara… I'm sorry," Hank gasps, clutching his ribs, "We'll find the Kalvar that did this…"

"You mean you didn't capture the bird that did this to- to her?! I'll do your job for you!" Kara snarls, flying through the roof of the bunker.

Hank transforms into J'onn, taking off after the distraught hero. She managed to get further away than he was expecting and he only managed to catch up to her when she landed in the warehouse they had raided earlier.

"Don't try to stop me!" Kara warns as she looks around for clues to the Kalvar's whereabouts. She didn't have to look for long as the Kalvar screeched before dive-bombing the hero. She grabbed the thing's talon and pulled the purple bird in half. Blood splattered Kara, J'onn, and the warehouse.

"She wouldn't have been in any danger had I been here!" Kara advanced on J'onn again as she threw the halves of the Kalvar to the side.

"I know," J'onn said as he took the now exhausted Kryptonian in his arms and flew back to the DEO.

A/N2: Don't hate me too much… Although killing off my favorite character was one of the hardest things I've written in such a long time. I'm also looking for a beta for the next 15-ish chapters. Message me if you're interested, I use Google Docs.
