Ashes to Ashes = Kidnapped

Ashes to Ashes 2.4 seems similar to Kidnapped as it has a girl going missing and an older female relative. In contrast to the older sister played by Barbara Crampton in Kidnapped, the older female relative in the Ashes to Ashes episode is that of an aunt.

Of the two women playing the older female relatives in their respective productions, I of course have no trouble picking Barbara who I love very very much.
