What this causes 1

"The Doctor's deduction in Act 1 that Meglos intends to use the Dodecahedron with the Screens of Zolfa-Thura directly motivates his later infiltration and sabotage of Meglos's control complex in the laboratory. The Doctor's understanding of the Dodecahedron's operational framework (Screens + control complex) sets up his later actions in Meglos's lab."
