Henderson discovers the Doctor’s alien heart

Dr. Henderson’s light box serves as the stage for the revelation of the Doctor’s alien anatomy.

Henderson’s interaction with it—pointing, questioning, ultimately dismissing—highlights his struggle to reconcile the evidence with his scientific training.
