The way Anduin closes his eyes and seems to be...reaching deep within himself to sense something, is purely fascinating for the Doctor. He's still learning so much about everyone in their group, their abilities, and he's equally learning to trust everyone's instincts. He has to, really, because they're all they have. Until Anduin's eyes open again, as well, the Doctor keeps close watch on their surroundings, to be cautious of any flying objects they might have to dodge again.

"Perfect sense," the Doctor observes, once Anduin reveals what he's sensed. "Embedded in this place, it must be, like the roots of a tree that bury themselves in the ground. And we're on the right path, that tells me, if it's getting darker. Well, best not to delay."

Only a moment's pause and the Doctor continues, leading them around the corner and towards what appears to be a greenhouse.
