Last year, Luke charmspeaked you to convince you that Kronos was doing the right thing. Overthrowing Olympus. You had went with him.
Grover, your boyfriend at the time, was absolutely heartbroken. But he never gave up hope. Ever. Over the course of the year you were gone, Grover tried pinching himself to wake up from this living nightmare.
He also regularly slept in your bed and took care of your kitten, Azalea, for you while you were gone. Grover had no idea if you'd come back. But he never gave up hope.
Until one day when Kronos suited you unfit for being a part of the rebels because you refused to break into Camp Half-Blood and hurt your friends. So, everyone deserted you.
You made one last resort. Make it back to camp. You were beaten up badly, but they'd be able to see you weren't a part of Kronos because the mark on your hand is fading slowly.
It took atleast 2 days to walk to camp. You were so tired, you collapsed right on Half-Blood Hill.
Clarisse, who had been feeding the dragon on the hill noticed you. She gasps when she sees how hurt you are. Especially since you were knocked clean out at hitting the ground.
"Chiron!!!"
Clarisse shouts, rushing to you.
