Imagine being King as well.
You're a Titan, and yet you still couldn't keep her safe. Even after sending her to another dimension. Even after all your anxiety about losing her.
She was the first friend you ever had. Your sister. Your hero. She saved you and your mother's lives multiple times. She listened to your stories and always tried so hard not to hurt your feelings even though she didn't believe you, and she talked you through your identity crisis when the world had shattered under your feet, and she knew all your toys' names, and she gave you her phone to watch stuff on but made sure you used it safely, and she chose to do a dangerous heist to rescue Francois for you, and she set time aside to make stupid puns with you because you were both just kids -
She was fourteen. She's dead. You're eight. You really don't feel like it, but somehow at the same time you feel younger and smaller than ever.
She begged you not to leave her once. Despite her family in the human realm, despite the danger and uncertainty all around, she wanted exactly what you did: to stick together. Maybe if you had, the two of you could have sorted things out with the Collector sooner. Or if you'd actually done something with all your godlike power, maybe Belos would already be defeated by now. You could have protected her. She always had your back, and when it mattered most you failed her.
Tears burn in your eyes and magic follows them. It rises in your throat like bile too, as blue as your blood. Belos wants a Titan's power? Fine. He can have everything you've got.
