Arc 20Time, Dueling, and Discovery
Manus tested his immunity to changes in time, developed his dueling skills, and guided Barty Jr. toward original magical research. He pursued new potion experiments and ended the stretch considering which classes to drop after Staky recognized his Time-Turner.
- Manus trained with Flitwick in the Room of Requirement, using non-verbal spells, Apparition, and his Statue Summoning Charm to win their duels.
- Manus helped Severus after Professor Staky questioned him under Veritaserum, while Lily and Severus enjoyed more free time from their usual training.
- Manus threw away the Time-Turner during its scheduled use and watched it turn to dust, concluding that the Soul System kept him immune to changes in his personal timeline.
- Manus encouraged Barty Jr. to rethink his paper on the Banishing Charm, demonstrated its uses in combat, and urged him to submit the completed work to British Oak Wand.
- Manus warned his classmates about Death Eaters near Hogsmeade and wrote to Dumbledore arguing that Filch was unsuited to his job at Hogwarts.
- Manus discussed Beauty Potions with Staky, then tested his crimson potion on Slimes and found that tiny doses delivered as a mist produced the best result.
- Manus used a second body to attend Ancient Runes and History of Magic at once, helped Black complete his assignment, and met Staky, who recognized his Time-Turner and advised him to drop Divination and Muggle Studies.
