"I made her a promise that I'm finding a hard time full-filling. She won't trust me until I do it." Promises were something that Poseidon and his linage seemed to have a hard time overcoming. But now he was more involved than ever. "I had to kill a child of mine once..." the wind cascaded against his face, "all because of a manipulative woman that couldn't tell me the truth. I've never gotten close to anyone again..." Theseus didn't expect Amphitrite to feel anything towards him. She could think he was just another monster like his father, but by showing his honesty he hoped it showed a difference.
"I don't want to be him." Her cruelty was needed. Words that were cruel, not actions. He needed someone to tell him what direction to take.
