Doctor and Cordo reunite with K9

The Doctor and Cordo escape the claustrophobic Undercity and climb to the subway where K9 remains. Their relief at finding him safe quickly gives way to suspicion as the Doctor questions K9's unexpected presence—a departure from orders to stay in the TARDIS. The lighthearted greeting mask the tension beneath, as the Doctor's offhand remark about an 'idea' hints at implications beyond the moment. This reunion serves as a pivot, unknowingly setting up the larger investigation into K9's unexplained actions and the looming threat of Company surveillance that will soon force the group to confront the Gatherer's conspiracy.
