Why This Matters Across Episodes
The longer arc this connection carries
This is a direct causal link. Marco Polo’s paranoia about escape attempts in Episode 18 leads to the hiding of the keys, which Ian later steals to protect Ping-Cho. This theft is the catalyst for Marco Polo’s anger in Episode 19.
