How these two moments in the story relate

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's evasion in Ep15 denies the Daleks their stolen property and forces them to develop new strategies (temporal tracking and pursuit) in Ep17 to deal with the intractable Doctor.
