Why This Matters Across Episodes
The longer arc this connection carries
Episode 19 establishes the Doctor's defiance against the Daleks and his willingness to manipulate them. This defiance culminates in Episode 21 where he not only resists but weaponizes the Daleks' own tactics against them, such as using one of their own as a shield.
About Causal Connections
