You had been at Camp with Luke since you were little. You both ran away from home at a young age and found camp with Thalia and Annabeth. You and Luke had grown up together and were best friends.

You were one of the three people Percy chose to bring with him on his quest to bring back the lighting bolt to Olympus.

Everyone had made it back to camp, but you wanted to surprise Luke. There was a rumor you stayed behind in Olympus to be with your godly parent. But you couldn't leave Luke behind.

You had Percy and Grover walk in first and tell you where he was, then you went to find him yourself.
