Thanks. I thought about warning for that, but I suspected people would figure out pretty quickly what was happening (or else skim that section and look for the explanation later).

Harry didn't mean to! Though I suspect that, even if he did know about Draco being hurt (and exactly what caused it) he would argue it was for Draco's own good, or that in the end it would hurt Draco less to be rejected now than it would later.
