Oh how did I get betrayed in earth or should I say Camp half blood and Olympus! It is easy ok this is what happened
{flash back}
I heard an shout or a scream to be correct. I being curious and all ran to the point of the scream. I saw an boy that was 6 foot tall with an stick. Wait a stick, how can he survive with that stick with 10 hellhound with 5 baby hellhound. Being a nice guy i helped him by killing all the hellhound with my sword going left to right to up to down and stabbing as well. It was easy since I killed Gaia. He quickly took his stick and knocked me out and said he helped me while I got knocked out by an baby hellhound.
