Grierson tracks Crayfords ship on schedule

Grierson and his scanner team lock onto Crayford’s XK-5 as it breaks orbit and begins its atmospheric approach. The moment is a hard-won vindication of long-range tracking after two years of dead silence—only to be undermined by the Doctor’s urgent warnings of android infiltrators. Faraday’s confidence in the vessel’s timely return clashes with the looming threat, turning a routine navigation fix into a ticking countdown. Every coordinate confirmed by Grierson becomes a potential breach point for the androids to exploit. The scanner room’s celebration is premature, its relief instantly tempered by the Doctor’s presence and the knowledge that Earth’s last clean ship may already be compromised before it lands.
