Why This Matters Across Episodes
The longer arc this connection carries
Marco Polo's abrupt change of plans due to Kublai Khan's orders (forcing travel to Shang-Tu and then the Summer Palace) escalates the conflict. Ian's desperation to confess the truth about time travel in Episode 19 is a direct result of the group's inability to reclaim the TARDIS and Marco's refusal to acknowledge their desperation.
