Conrad wasn't without his own misgivings. Natalie had burned him. She had burned him good. Even better he'd turned into a complete asshole when he flipped to his younger self. He had no control or knew when that would haunt them again. He understood Natalie needed her space, he needed his own---but there were still some scars on the heart that he may have forgiven not necessarily let go.
His eyes were closed as he idly let his fingers play in her hair. He didn't ask her what was wrong, there was a silent barrier between them both as they played on each other's fears and worries.
One day Natalie might just let go and fly away. It was in her spirit.
