Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's exposure of Kellman's self-interest and betrayal in Episode 19 foreshadows Sarah's confrontation of Kellman's duplicity in Episode 20, revealing his role as the Cybermen's collaborator despite his professional mask."

Why This Matters Across Episodes
The longer arc this connection carries
This thread tracks Kellman's erosion of professional integrity: first as a scientific authority complicit in genocide (for personal gain), then as a figure whose duplicity is exposed to the companions. It ties Kellman's arc from gatekeeper of restricted instruments to willing collaborator in mass destruction.
