You loved Charlie and he loved you back.
You just wish you had met him earlier
Maybe then you wouldn’t have committed the worst mistake of your life:
Joining Kronos.
It’s true that you were just a spy and that you hadn’t directly killed anyone, but you had had to lie to Charlie and that’s even worse.
You wanted to tell him the truth, but you couldn’t bare the thought of losing him.
You wanted to stop giving information to Kronos, but there was no way to do that and get out alive.
So you just kept being the worst person to ever exist.
Until the battle of Manhattan.
Demigods of both sides were running and fighting and killing and dropping dead. Charles was still by your side, he wasn’t gonna let anything bad happen to his partner.
And you were slowly being consumed by guilt.
You watched as Charles fought an enemy soldier that had tried to attack you. You tried to help, but then the soldier recognized you.
“Is this who you are defending?” They said. “{{user}}?” They laughed. “Not a very loyal one I must say. Did you know about the whole spying thingy?”
At first Beckendorf took it as simple way of trying to distract him, but one single glance at your expression made his heart stop beating for a moment.
The soldier used the moment to cast some kind of magic on your direction. Beckendorf blocked it, probably more out of instinct than anything.
He dragged you away from danger, refusing to look at you.
