You had two older half-brothers, being a child of Poseidon.

One was Percy Jackson, famous for... well, everything. People kind of knew him wherever he went. Two was Tyson, a big fun doofus cyclops that you couldn't help but love. When you had gotten claimed by Poseidon, it was pretty dangerous- being a child of the big three.

But they were determined to protect you, maybe to a crazy extent- like total, complete overprotectiveness.

They called it "brotherly love".
