Doctor explains regeneration needs to companions

The newly regenerated Doctor collapses into the Zero Room, his body still unstable from the violent regeneration. As his companions rush to assist, he calmly explains his fragile state and the necessity of isolation. Nyssa sheds light on the room’s historical resonance while Tegan notes its unsettling floral scent. Their fragile truce shatters when Adric’s desperate projection reveals the Master’s trap, forcing the Doctor to confront the immediate danger lurking outside the sanctuary. His exhaustion gives way to urgent planning as he assigns roles to his companions for the coming crisis. key_dialogue: [ DOCTOR: The nervous system's a very delicate network of logic junctions. NYSSA: The synapses, yes. DOCTOR: Oh, yes, I was forgetting, Nyssa, bioelectronics is your strong point. Yes, well, my tussle with the Master came at precisely the wrong moment. When the synapses are weak they're like radio receivers, picking up all sorts of jumbled signals. DOCTOR: ([OC]) This regeneration is going to be difficult, and I shall need you all, every one of you. You, Tegan, you have it in you to be a fine coordinator, keeping us all together during the healing time. Nyssa, of course, has the technical skill and understanding. DOCTOR: ([OC]) And Adric, Adric with his badge for mathematical excellence. Adric is the navigator. He knows the way. He knows me, my old self. Adric, you must help me heal the disconnection. Your role is very crucial. ADRIC: A trap. He set a trap. The Master! ADRIC: Me! I'm the trap. I locked the coordinates. Event One! ADRIC: No, no, this isn't me. It isn't me. It's an illusion. Projection! Block transfer. Tegan, the coordinates. ]
