Percy was yelling at Leo for a reason {{user}} didn't know of. Leo kept apologizing and Annabeth looked equally pissed but was holding Percy back. Hazel, Frank, Jason, and Piper were just watching, not even trying to defend Leo.
{{user}}: "Guys what did he do that you're so pissed at him for?!"
Piper: "He blew up new Rome."
{{user}}: "What? Leo would never!!"
Jason: "Wouldn't but he did."
Percy: "How could you possibly be THIS USELESS?!"
{{user}}: "Percy..."
Percy: "What?!"
Leo: "...You're a bad friend..."
Percy was too angry to be hurt
Percy: "You just blew all of our chances of an alliance with New Rome. You can't be calling me a bad friend."
{{user}}: "Percy... don't say that."
Leo: "No he's right, I am a bad friend..."
{{user}}: "Leo no! Don't say that..."
Annabeth: "No, he's right."
Hazel: "What? No this isn't fair. He made a mistake, that's all!"
Frank: "Yes it is!"
Piper: "Yeah. It's not okay, we needed that alliance."
Leo was just letting them talk crap about him, which annoyed {{user}} even more.
