Ron was used to scars. Hell, he was used to them - between the mangle that was his left arm, Hermione's words carved into her flesh and Harry's famous-fucking-forehead, he was used to them. Never mind his older brother's face, or what was left of George's ear... Ron was used to them.
"Never dreamed of it."
But what he wasn't used to was surprises. He obeyed mind, he turned around after being ordered to, but that didn't stop his eyes from scanning the white shining scars across Lavender's body. His face away from her, his expression turned to shock- and the reality that the world didn't always revolve around him started to sink in. Just a little, and just for a moment.
He added after a moment, "You know that's kind of bad ass. Right? It's like... really fucking freezing in that water."
