"Think of it as spokes on a wheel," Harry explained. "Each spoke goes to an individual family member, then there's a collective sense mixing from the family hub, probably buried under The Burrow somewhere. What I want to do is hijack Percy's personal spoke, then create a sort of tributary into the connection Ron has to you. So whenever Ron tries to hurt you along the Weasley line, it will redirect into me, instead, but still feel like it's going along the family connection."
