Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Jo Grant's mind-controlled trauma (from Episode 2) catalyzes the Doctor's urgent investigation into the Autons' plastic weapons in Episode 4, as he examines the daffodil's weaponized programming to prevent further hypnotic infiltration."

Why This Matters Across Episodes
The longer arc this connection carries
The immediate fallout of Jo's mind control (Episode 2) directly escalates the plot in Episode 4, where the Doctor's analysis of the daffodil's hypnotic/molecular programming is framed as a response to the Master's earlier psychological assault on Jo. This creates a causal chain from her trauma to the central threat's escalation.
