Master sighting ignites base security crisis

Jo’s sudden sighting of the Master triggers immediate chaos on the naval base. The Doctor’s insistence on a full security alert clashes with Hart’s skepticism, creating a standoff between urgency and institutional caution. Trenchard’s earlier feigned casualness about the golf tournament now stands exposed as the calculated manipulation it was, as the Doctor pieces together the colonel’s role in the conspiracy. The revelation transforms a simmering internal threat into a visible danger, forcing everyone to confront the scale of the conspiracy while the base’s reptilian predator lurks unseen.
