Well it's not like Natsu is shy. But she'll remember. And probably try to make him repay the favor. If she happened to look a little amused by his response well, it was hard to tell with a mask on and a snorkel in her mouth. Either way she dove down and made it about ten feet before the pressure of the water started pressing in on her. It made her head ache but she continued down making it to about seventeen and watching the shark swirl below her, moving smoothly through the water, it swam farther away then turned, rising far enough to circle her from about eight feet away. She could see people through the windows but they were pretty far back and mostly shadowed by how much water was between them. There was some motion like someone leaned closer trying to see and she had to be careful not to laugh and lose what air she had held. She turned back to watch the shark circle again, enormous next to her small form. It swam in closer but never close enough for her to reach out and touch it. Which was disappointing.

She stayed down as long as she could, treading water slowly before the need for air kicked in and she hand to make her way back to the surface, she spit the water out of the snorkel in Reid's general direction, dipping her head down again as she started to breath and looking to see where the shark was. It was still circling below her.

Lifting her head she slid the snorkel out of her mouth and left it hanging from the glasses, then lifted those to look at Reid with excitement. "It swam around me!" It took her a moment to catch her breath and she looked back down. "I want to touch it." There was definitely excitement in her voice now.
