Smiling softly at his words of determination, she willed him a successful attempt. Not that it would actually do anything other than that she was mentally giving him her support. "It's ok; you can do this," she assured him.
A bit delayed to his question, she nodded her head, even though he was already laying back. It was then that she noticed him shivering. Goodness! The poor guy. No wonder he was struggling with the floating. It was probably so hard because he was freezing. Although fear was usually a pretty good block for doing something successfully.
She let him float for a bit with her assistance, but really, she was concerned about his shivering, and after a moment, helped him to his feet again. "Let's take a break, shall we? I'm sure you don't want me going all puddly on you." With that, she attempted to take his hand and lead him out of the water. She had every intention of snuggling up to him on shore to give him her body heat. Hey, she'd totally seen that in the movies!
