In that moment, he felt Voldemort recoil not from the threat to life, but from the threat of pain.

Harry couldn’t help but grin viciously at this revelation.

After hearing the full prophecy later that night, Harry couldn’t help but celebrate in the lesson Bellatrix had so generously taught him.

While he may not be able to bring himself to truly desire to inflict pain for the joy of it typically; for Voldemort he was willing make an exception.

No, he would gleefully revel in it.

He would savor it.

And if his genuine joy happened to bleed through into Voldemort and cause further pain, all the better.
