How these two moments in the story relate

Why This Matters Across Episodes
The longer arc this connection carries
Striker's orchestrated isolation of Tegan in Ep 17 creates the Doctor's suspicion that she is a target. This suspicion escalates into action in Ep 18 when the Doctor instructs Turlough to 'Find where Marriner's taken Tegan,' directly responding to the earlier separation.
