Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's establishment of the school as a defensive base in Episode 3 (disabling the transmat, forcing Daleks to focus forces) creates the conditions for Episode 4 where he must rally these base defenses against the Imperial Daleks' shuttlecraft."

Why This Matters Across Episodes
The longer arc this connection carries
This causal link shows the Doctor's long-term planning spanning episodes - his defensive preparations in Episode 3 directly enable his tactical response in Episode 4 when new Dalek factions arrive.
