Why This Matters Across Episodes
The longer arc this connection carries
The chain of events from Ping-Cho secretly passing the TARDIS key to Susan (Episode 18) to Kuiju stealing the TARDIS (Episode 19) illustrates how initial small acts of deception lead to significant escalations. This reflects the domino effect of the Doctor's companions' actions and Tegana's manipulations.
