Nemesis Fragments Mathematical Proofs

A bundled collection of mathematical papers belonging to the 17th-century mathematicians whose groundwork forecasted the Nemesis device’s theft. The documents are written on aged vellum and secured with leather thongs, the margins annotated with cryptic calculations and astronomical charts. Ace gathers these as critical artifacts, their proofs foreshadowing the precise thefts the Cybermen would later attempt to execute.

S25E10 · Silver Nemesis Part 3

Ace questions the Doctor’s plan in 1638

Ace gathers the mathematicians’ papers, their cryptic calculations central to predicting the Cybermen's theft plans. The Doctor references their theft indirectly through chess metaphors, treating them as bait or critical intelligence rather than mere documents.

Before: Scattered on a table in Lady Peinforte’s manor, vulnerable to theft

After: Secured by Ace in a rolled bundle, the papers become a vital component they transport away

S25E10 · Silver Nemesis Part 3

Doctor and Ace secure critical artifacts

The mathematicians' papers are carefully rolled by Ace, their antiquated provenance highlighted by the Doctor's chess metaphors that map theft across centuries. These proofs encode the temporal mechanics of the Nemesis device's theft, making them essential to comprehending—and preventing—the Cybermen's scheme. Their removal symbolizes Ace's growing mastery of temporal patterns.

Before: Scattered across Lady Peinforte's manor, vulnerable to theft or discovery by enemies

After: Secured in Ace's possession after being methodically collected, marking a critical step in dismantling the Cybermen's plot
