Narrative Connection
How these two moments in the story relate

The narrative assertion
"Both episodes frame the submarine crew as operating in environments where the enemy is physically unseen but mechanically undeniable—sonar vs. breached bulkheads in Part 3 and the Sea Devil attack in Part 4."

Why This Matters Across Episodes
The longer arc this connection carries
The theme of unknown threats operating beyond human perception (sonar pings failing to reveal, then physical invasion through breached metal) is carried forward and realized in the physical attack.
