What this causes 2

"The Doctor’s revelation that he inverted the Dodecahedron’s controls directly causes Meglos’s frenzied attempt to stop the countdown in Act 3. This revelation is the catalyst for Meglos’s final, desperate actions and Grugger’s fatal mistake."

S18E8 · Meglos Part 4

"The Doctor and Meglos’s witty verbal sparring (prison cell) echoes the Doctor’s casual trust in the Tardis’s ability to dematerialize (TARDIS doorway). Both reflect confidence in machinery under their control — but in the Doctor’s case, it’s earned; in Meglos’s, it’s misplaced, foreshadowing failure."

Key Dialogue

"DOCTOR: Yes, they've not been very clever, have they, unlike us."
"DOCTOR: I inverted your control setting. If he starts the countdown, he'll destroy himself, as well as you and me and, well, the whole planet, of course."
