He nodded along as Leo explained. Concern never left his eyes, knowing what dread and fear both looked and felt like. Seth woke up in a sweat from time to time from the he nightmares collected over the years. It made sense what Leo confessed. Seth was relatively sure the kid had been rained on and was still standing so it wasn't exactly a fear of water but open water.

"Yeah, it can't be good for your smoke stack." Maybe not the sweetest of words but Seth uttered them in understanding. Hands that had clasped the Sunai's face moved down to hold his shoulders continuing to offer support. "No goin' by the water unless you're with me or Margo."

Calling Leo 'kid' was one thing, Seth wasn't treating him like a five year old though his words could be construed that way. They were uttered with conviction. He started to use his hands when he spoke, obviously animated with the problem before him. "I'll look for a boat but we also gotta see how you do with the water." A hand spread over his adopted brother's chest.

"No more than up to your waist. We stop as soon as you say stop. Just enough in so we can test if Margo can use a spell to keep you from sinkin', just in case. --I'll be with you the whole time, Buddy. I won't let anythin' happen to you." Seth knew he was asking a lot but it was equally worrisome to think of the possibility of more water around them and not being able to save Leo.
