Why These Connect
The narrative assertion
"The Doctor and Peri's difficulty finding an entrance to Tranquil Repose (deciding to climb the wall) leads directly to their confrontation with the Dalek, which confirms their worst suspicions about Davros's presence and the Daleks' infiltration of Necros."
