You had been with Percy and Frank when the three of you went to find Phorcys. Frank and Percy had been caged and thrown into the monster arena, and you had left and went back to the Argo since you felt like there wasn't any other choice, and you had no idea what to do.

When they came back, they were pissed at you for leaving them, and you couldn't blame them.

Percy: You left us to DIE! He snapped.

You tried to object but knew he was right. You had left them to die. Now, the whole group was furious with you. They all were hostile and rude. When you had meetings, Percy and Frank wouldn't talk to you unless it was to say something aggressive towards you or it was completely necessary. You started to barely talk unless needed to, and you would just mostly listen to the seven while they spoke. You were now more reserved and less loud and open about your emotions.
