Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's earlier deafness to Ian's skepticism forces him to confront the consequences of his arrogance when he must rescue his companions from the guillotine. This reflects a shift from dismissive confidence to humility-driven action.
