Nope, I was talking about the Greek and Roman camps, as the first line of his comments was "I don't think there will be a fight between the Greeks and Romans because..."

If we are just going by the 6 (seven counting Hedge) on the Argo II:
 * 1) Dating is messy. After meeting Hercules and Achelous, Piper does have come doubts about Jason. If the two don't fight, it isn't a realistic relationship.
 * 2) Yes their friendship has grown, but it isn't perfect. In fact, Frank and Hazel end up having an argument because of Hazel constantly pairing herself up with Leo. Not to mention Frank is normally on the receiving end of Leo's pranks and jokes.
 * 3) Hazel and Nico are friendly with each other, but Jason doesn't really trust Nico after finding out he is a Greek demigod and lied to him and Camp Jupiter. It was actually the reason Hazel became so angry with everyone when discussion how to save Nico.
 * 4) Jason and Leo are best friends, but once again look at 2. Also, even if Jason and Leo are best friends, Leo still feels inferior to Jason which could lead to an argument.
