After tonight’s cliffhanger, we’re faced with another week of speculation as we await part two, Cold Blood, which continues from tonight’s episode and sees Earth face the dawn of a new age of harmony – or the start of its final war.

The Doctor faces his most difficult challenge yet, finding himself in a battle in which he cannot take sides. Cold Blood airs 29th May on BBC1/HD at the slightly later time of 19:00, followed by Confidential, What Goes On Tour, at 19:50 on BBC3 and 23:15 on the HD channel.
