Harry didn’t even realise that he and Ron had arrived at the hidden training room until Ron was pushing the doors open. He’d completely forgotten that he’d told Ron about the room and his sword after the First Task, along with his strange training regimen. Numbly Harry went inside, heading straight to the wall and picked up the Serpent Slayer replica. The nearby dummies activated without a word and started to throw jets of harmless light at him, forcing Harry to either deflect with a Shield Charm, block with his sword or simply roll out of the way.
