If this is discussed elsewhere, just point me in the right direction, but I was wondering about what Syl said to Kaladin in Way of Kings. In chapter 2, "She bent down, looking at his hand from different angles, like a child expecting to find a hidden piece of candy. “What is it?” Her voice was like a whisper. “You can show me. I won’t tell anyone. Is it a treasure? Have you cut off a piece of the night’s cloak and tucked it away? Is it the heart of a beetle, so tiny yet powerful?”
Any theroies on what these two expressions mean? I saw one person say the heart of a beetle might be like a tiny gemheart, but would that really be powerful? And what does the night's cloak mean? I haven't heard a single theory. Maybe someone could bring it up at a BS Q&A...
