Nyssa aids Tegan up treacherous rocks

With Castrovalva’s shifting walls and the Master’s net tightening around them, Nyssa leverages her knowledge of the Doctor’s principles of initiative and improvisation to spur Tegan toward the entrance. Tegan’s refusal to indulge hypotheticals contrasts with the gravity of their situation, but both prioritize movement even when no immediate solution exists. Clambering up the jagged rocks, Nyssa physically lifts Tegan into the fissure, their bodily cooperation an unspoken vow to reunite with the Doctor before Adric’s spectral warnings or the Master’s cohesion spell can isolate them further. This moment, though brief, deepens their partnership under extreme pressure and tests each woman’s resolve in the Doctor’s absence. key_dialogue: [ NYSSA: Closed without a trace. If we had a three micron beam wedge though. TEGAN: Well, we haven't. NYSSA: I said if. You taught me about if, remember? TEGAN: It's not that sort of if. It's what we can do, with what we've got, if only we used a bit of initiative. Come on. ]
