"Rose" also featured an Auton facsimile that could change the shape of its features and limbs, and established that the Nestenes animate the Autons by means of telepathic projection.

It is not yet clear if the war mentioned was also the motivation behind their earlier invasions or a recent development, but it is likely to be the Time War that is featured in subsequent episodes of the series.
