Doctor and Leela begin perilous journey inside his mind

The miniaturized Doctor and Leela 2 step into the treacherous landscape of the Doctor's brain, mentally equipped for the peril ahead. Leela 2's knife becomes both compass and defense as she probes the unknown terrain while the Doctor admits his uncertainty about the path forward. His deferral to her instincts underscores the dangerous gamble they are taking, trusting her primal abilities to guide them past the virus and its minions. Each step inward may determine whether the Nucleus of the Swarm claims their minds or if they can reclaim the Doctor's mind from within. key_dialogue: [ DOCTOR 2ND: After you
