Helping Blaze into the cavern, you notice that she quickly covers her chest the moment she gets a chance. "Don't worry about it Blaze, you look great." You tell her, trying to keep her from being too embarrassed. "And besides, it's just the two of us here. You don't need to worry about anyone else seeing you." Somewhat comforted by that fact, Blaze timidly moves her arms out from over her chest, once again revealing her small, perky breasts. Shortly after, you start thinking about kissing her, as it's clear she's fighting the urge to do the same, but the only reason she'd have to fight the urge would be her concern for Cream and Marine, so you set the thought aside, hoping for a "hero's reward" after finding the missing two. Looking around the cave, you don't find much of anything. You only notice two choices of action, either returning to the water or following the cave to see where it leads.

Get back in the water or follow the cave?
