Ch. 401It Was Definitely Not True That Gryffindor Students Only Knew How to Shout Their Support
Dylan studied the collective desire powering the Projection Screen and realized how individual will could flow with consensus magic. As the other Champions faced Grindylows, the spectators watched their progress and noticed that the Black Lake Mermaids had changed.
- Dylan used a spell to strengthen his soul perception, resisted the spectators' collective desire to see the competition, and uncovered how consensus magic guided and amplified the Projection Screen.
- Ludo Bagman reported that Dylan had stopped moving, while Karkaroff and Madame Maxime hoped he was recovering; Dumbledore suspected he was studying magic and predicted a surprise.
- Ravenclaw students Michael Corner, Anthony Goldstein, and Terry Boot speculated about why Dylan had stopped, and Bagman showed Harry, Cedric, and Draco encountering four Grindylows.
- Draco's protective magic deflected a Grindylow's spikes, and he joined Harry and Cedric in driving the creatures away.
- Michael noticed that the Mermaids in the image looked neater and had shinier scales than before, then angrily challenged Anthony after Anthony teased him about searching for female Mermaids.
