TARDIS gravity fails and Doctor warns of danger

The Doctor attempts to reassure Tegan about her lingering trauma from the Mara but is abruptly distracted when the TARDIS shakes violently. A malfunction in the warp ellipse suggests a fixed object in time and space is perilously close. Nyssa calculates the probability against such a coincidence as several billion to one. The Doctor’s grave tone replaces comfort with alarm, signaling something far worse than a simple breakdown. Tegan’s longing to return home goes unanswered as cosmic forces threaten the ship’s stability. key_dialogue: [ TEMPORARILY CONTAMINATED DOCTOR: I'm afraid it's much more serious than that. ]
