Why This Matters Across Episodes
The longer arc this connection carries
Jo's insight in Episode 3 ('will up a door') establishes the thematic and tactical importance of willpower and unity among the Doctors. This directly foreshadows and enables the Doctors' later evasion via the TARDIS in Episode 4, where their combined wills (and Jo's continued facilitation) lead to a desperate evacuation—elevating her from problem-solving aide to key enabler of survival.

A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
