Tidas took a step between his wife and his brother. He was far too close to his wife's face for his comfort; or Skye's, for that matter. She didn't want to flinch away when he came close. The princess got the distinct feeling that he wanted her to be rattled by him, so she refused to give in. She felt like he wanted to reach out to her, but thankfully her husband had intervened. Marco made her skin crawl, and caused warning sirens to blare in her head. Every instinct in her screamed one thing at her: Marco was a threat.
Right as Tidas got between them, he felt his brother's magic tick up. He had Skye move back a bit, just in case his question caused a bad reaction. The prince looked his oldest brother in the eyes, and asked flat out; "Why do I sense magic from you, Marco?"
Leaning back to avoid his little brother's shoulder, Marco replied; "Because I have an amulet that was infused with it."
