"I don't want a temporary place!" She was being spoiled because she was scared, and as a halfling of Poseidon's she was taking this in the way he would--by putting up walls around herself. She had spent a long time under his care and now that attitutude, that coldness that he had flipped on was transferring over to her. In some ways it was a test to see how the girl responded. She was just his little rat in a maze, only she didn't see it. She was blinded by the hurt and she didn't want to go through this again. She already had lost her mother years ago to a Japanese demon that ate her and wore her face like a wolf in sheeps clothing. Raiden had long since covered that memory up and tried to move on, and now everything was falling on her like a ton of bricks. Halfling or not she was starting to crack and lash out.
Briareos stepped towards the girl, ready to shove her towards Thetis, but he didn't want to touch her. It would show that he understood more than he let her believe, and he didn't want her to think he actually wanted her to stay.
