"No Grace!" I yelled back at her.

"Why are we using last names?"

" I have no idea," I said.

"Come on let's go," I said. I grabbed her arm. She flinched and i saw bruises on her wrist.

"Thals?"I asked worried

"Thalia please tell me, " I said really worried.

"Leave me alone Nico!"she said

"Is it Luke?" I said

" No!" she said

" Thalia you can trust me," I said

"Promise?" she asked

"Promise," I said
