He figured that if anyone came too close he could also hit them with it, which was a definite viable option. He'd seen his sister talking to Neville - that made him relax. Merlin, that kid had been through more than enough, being at Rosier's beck and call. Ron couldn't even imagine. That bloke was unhinged...
He saw Anthony and gave him a nudge with one elbow. "Hey, mate. Don't look like that, 'cause you're just gonna give them a challenge, y'know?" Ron was difficult himself - but he knew when to harness it in. The least thing any of them wanted to do was provoke. "Don't give them the satisfaction."
