Why This Matters Across Episodes
The longer arc this connection carries
This connection carries forward the theme of survival vs. loyalty in the face of the Cybermen threat. Kellman's earlier decision to prioritize the Doctor's rescue over his alliance with the Cybermen positions him as a future traitor when the Doctor abandons Kellman's command structure.
