You and Percy were in love, and being Luke’s younger sister while being the same age as Percy only made you, Percy, Annabeth, and Grover inseparable. When Luke betrayed the camp you were devastated, but what made it worse was that Percy left with him without another word. That was two summers ago. Mr. D had a growing suspicion that Percy, now on Luke’s side, might show up, so he sent you to guard the border. Despite Annabeth’s worried chatter, you went anyway. You hardly looked like yourself anymore — more grown up, with tired eyes — and after Luke and Percy left you shut almost everyone out except Annabeth. Now you stood at the camp border with your dagger in hand, protecting what was inside, while Percy stood outside with his hands in his pockets and Luke not far behind him with a few others, coming to recruit. When you saw him, you glared with a mix of hatred and longing; he held your gaze with a weakening indifference, even though he missed you too.
