Dear Alex,

I just wanted it to be clear that none of this is your fault. I love you. Always have, and always will. This doesn't change that. Nothing ever could.

I'm trading myself to Cadmus tonight. It's the only way they'll give back Jeremiah. You made it clear that if Jeremiah was here and I wasn't, that would give you the happiness you so deserve. And all I've ever wanted is for you to be happy. You've done so much for me, and don't deserve all of the things I've done to screw up your family.

I know I've ruined your family. You. Our relationship. I've ruined everything. So I'll do what I've never done: finally listen to you. I'll trade myself in. It's okay though because you'll finally have Jeremiah back. You'll be a complete family.

I told you I would die for this family, and you didn't believe me. You dared me to trade myself in. But what you didn't consider is that I was dead serious. I'm going. And when I'm gone, and your father is back, everything will finally be okay for you. And I'm so thankful that the last thing I do on this planet is give you the happiness you've always deserved, but never had.

You told me that I wasn't part of your family anymore. And rightfully so. You should never have taken me in the first place. All I've done since then is stress you out, and put pressure on your from your parents. You've had to sacrifice everything for me. You told me you let go of all your dreams to be there for me. And you shouldn't have.

I didn't deserve it. And still don't. I didn't deserve your love, or anything your family gave to me. I haven't done anything to deserve everything you've given me. Not a single thing. But I'm hoping maybe tonight, I can redeem myself. I know it can't make up for everything I've taken away from you, but hope it'll help at least a little. I've accepted that I'm no longer your family. That you don't want me. But, despite that, you will always be mine. Thank you for everything you've done for me.

You told me I should have never come to Earth. That you would have preferred if I stayed in the Phantom Zone and suffered. And so do I. You deserve happiness and I took it all away. I would happily go back and stay there for the rest of my life if it could give you back everything I took away. But it won't help. So I'm doing the one thing that will: getting your father back.

I know you consider me a waste of your time. A waste of your life. Every minute you spent on me was just... wasted. And I agree. I shouldn't have taken everything away. I would gladly do anything to take away all of the pain I've brought you. But I can't. I'm just hoping that Jeremiah is the one person who can.

I'm sorry that all I've ever done is hold you back. From being happy. From reaching your full potential. From your goals, your dreams. I've just been a heavy burden weighing you down, and you did absolutely nothing to deserve that. And I'm just... sorry.

I love you. I hope you find the happiness that you deserve. I hope you finally have the family that you always wanted, not the one that I ruined. I hope that when I'm gone, you can finally do all the things that being my sister prevented you from experiencing.

None of this is your fault. Thank you for everything you've done for me. Thank you for loving me unconditionally, even if you said it was forced. You told me that your love for me was fake, but it felt real to me, and that's what I needed when I was just a broken and sad little girl. Thank you for always being there for me. It's even more special to me looking back now that I know that you only did so because you felt obligated. You stood by me, even when you didn't want to.

You have changed me for the better. I'm just sorry that I changed you for the worse, that I couldn't do the same for you that you did for me. I thank Rao everyday that by some miracle, you came into my life. I just wish He had done something to benefit you too.

I hope you live a good and full life. A happy one. I hope you have beautiful kids someday, with someone you love. I hope you do everything you couldn't do because of me. I love you, and I'll always love you. I'll love you even when I'm gone.

You have been the light of my life,
I love you with everything that I am.

I'm sorry,
Kara

Alex tried so hard to keep it all in. To stay strong. But her heart didn't allow her. Alex felt a sharp pain in her chest every time her little sister repeated one of the horrible things Alex had said to her.

She felt like she couldn't breathe. All the air had been sucked out of her lungs.

It felt as if someone had reached into her chest and yanked her heart out, only to rip it up in front of her.

Alex couldn't do anything. She was frozen. Stuck. The pain in her chest wouldn't allow her to move anywhere. The only thing she could do was tuck her head into her knees.

And cry.

She shouldn't have said any of that. She never meant it. Alex couldn't believe any of those words had come out of her mouth.

Kara was going to leave this earth truly believing that Alex hated her. That all Kara had ever been was a burden. When in fact, she was the opposite.

Kara was her everything, her whole world. Her little sister was her life, everything that was good. Alex loved her with her whole soul, her entire heart.

Alex would have never experienced true joy- true happiness, without her sister there by her side. Alex had never even paid any attention to Kara when she first got to Earth, even when Kara stuck by her side.

She was in the stands of every soccer game. She was front and center at every science fair. The first to greet her when she came back from a friend's house. The first to comfort her when something was wrong. She was always there for Alex, when her big sister refused to return the favor.

Alex didn't feel like she deserved that kind of unconditional support. And it broke her that Kara thought of herself as a harm to Alex.

Her own baby sister.

Kara was going to die tonight, thinking that she had ruined everything. That she would have been better off suffering and slowly withering away in the Phantom Zone.

Firmly believing that everything Alex had told her was true. That her big sister, who was supposed to support and love her unconditionally, actually wanted her dead.

Kara was going to die tonight.

Oh my god, Kara was going to die tonight.

Kara is getting ready to trade herself in as we speak. I can't believe... She's actually going to... shit, shit, shit.

My baby sister's going to die tonight.

Alex jolted to her feet, and tucked the note into her pocket. She ripped open the door and sprinted out. She needed to find Winn.

Kara was going to die tonight. And she was the only one who could clean up this mess that she made.

Alex had three hours to stop this from happening. And she wouldn't waste a single second.

Alex wiped her tears away.

And she ran.
