Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor and Peri's arrival in 1985 London via a malfunctioning TARDIS (source) directly leads to their confrontation with the Cybermen's plan and Lytton's heist, culminating in the Doctor's use of the TARDIS as a bomb threat (target)."

Why This Matters Across Episodes
The longer arc this connection carries
The unstable TARDIS landing sets the entire plot in motion, allowing the Doctor to accidentally foil Lytton's heist and stumble into the Cybermen's operation, which is the central conflict of Episode 2.
About Causal Connections
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.
