Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Barbara’s interrogation of Ling-Tau about the brutal Mongol relay system (Ep 18) mirrors Marco Polo’s later interrogation of Ian about the TARDIS and its travel mechanism (Ep 19), both highlighting the brutal efficiency of Mongol authority and control."

Why This Matters Across Episodes
The longer arc this connection carries
This creates a thematic parallel between the inhuman efficiency of Mongol systems (relay horses, personal endurance) and Marco’s rigid control over the TARDIS, reinforcing the idea of oppressive structure.
