Ophelia was in the midst of a conversation when she noticed the Hermes kids stand. Now that everyone was being claimed by the age of thirteen, they numbers were as large... But that didn't mean they weren't still the largest cabin in the camp. One of the boys whistled and a bunch of people from other tables and pounced on the Romans. It didn't matter how great fighters these guys were, they were greatly outnumbered. She stood as they grabbed the Romans and pulled them out of their tables and took off out of the Mess Hall. 

Her and probably every other confused Camper followed. She laughed as the Romans were carried to the end of the dock and tossed into the water. Connor Stoll stood at the end, his hands in the air, "Welcome to Camp Half-Blood."

Ophelia laughed more still before she ran to the end of the dock and jumped in. She was followed by a few other adventurous campers, some of them being people who had just thrown the Romans in, most likely to avoid retaliation.
