Episode 3: Needle
Vireo has escaped from her room and into an abandoned warehouse. She pursued by the Doctor and Mother, who are now trying to convince her to come with them for treatment. Vireo has a tentative hold on reality and she slips in and out of time. Her 16th-century religious beliefs seem to run up against the 19th-century psychoanalysis that the Doctor is proposing. Even the Doctor and Mother seem to slip in and out of time now, bringing their sense of reality into question. The Doctor eventually traps Vireo and takes her back to his office for further testing.
