The Doctor arrives at UNIT Headquarters, meeting up with their leader Kate Lethbridge-Stewart and several other members of UNIT. The Doctor asks them to try and identify the mysterious woman who has appeared as various other faces in his previous adventures. UNIT is able to identify her as Susan Triad, who is the head of S Triad Technology. The group believe S Triad to be an anagram of TARDIS, and believe it to be a trap. The Doctor additionally believes that Triad may be his granddaughter Susan Foreman. Ruby leaves with Rose Noble in order to retrieve a VHS containing security footage from the night Ruby was abandoned, with the Doctor and Ruby hoping to identify Ruby's mother through the usage of UNIT's technology.
Ruby and Rose return to Ruby's apartment, where Ruby's mother Carla joins them. She has their neighbour Mrs. Flood look after Cherry. As they leave, Flood declares, "He waits no more," as a storm approaches. Ruby and Rose return to UNIT headquarters, where they use a "Time Window" in order to recreate the night Ruby was abandoned, entering it alongside UNIT colonel Chidozie. A hooded figure, believed to be Ruby's mother, points at the Doctor, who asks Chidozie to see if there was anything else the figure could have been pointing at. Chidozie sees nothing, and as the figure disappears, a mysterious swirling vortex appears where Chidozie stood. After asking him questions, the Window overloads, leaving behind Chidozie's dead body.
The Doctor goes with Mel to talk to Triad as she prepares for an international technology launch broadcast. The Doctor does not recognise Triad as his granddaughter, and realises that she experiences dreams of her other existences. UNIT view the vortex on the VHS and, using image enhancing technology, are able to determine that the TARDIS was at the centre of the vortex. UNIT identifies a being surrounding the TARDIS as it begins to groan. Harriet, a member of UNIT, is revealed to be a harbinger of The One Who Waits, who materialises around the TARDIS and reveals himself as Sutekh, the god of death. Triad breaks down over the memories of her dreams during the broadcast, before Sutekh possesses her and attempts to kill the Doctor.
