Why These Connect
The narrative assertion
"Herbert’s stowing away on the TARDIS (motivated by his fascination with time travel) directly results in the Doctor’s reluctant agreement to return a mirror to him later. This minor but recurring detail humanizes the stakes of the Doctor’s journey and ties the Victorian era to the TARDIS’s narrative."
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.
