With a very careful aim, K-9 shot holes in each of the webs holding the team, and everyone slowly eased themselves back out and onto the cave floor.
The monkey spiders seemed to have vanished entirely, and the Witches were now silent.
Graham peered suspiciously at the statues. "Are them Witches done now? I don't know how you tell."
"The one good thing about Wayward Witches is that the less body mass they have, the less effective they become, almost instantly. They might be able to nibble on a few more wishes here and there, but once a statue starts eroding it's hard to stop it," the Doctor explained.
"Thanks for coming back, K-9," Yaz said, bending down to him. "You saved our lives."
"Negative, mistress. Without prior knowledge of your neck adornment, I would not have been able to neutralise the threat alone."
"I think you were right, Graham," Yaz said, gently stroking her necklace. "I really should tell my sister how useful this thing is."
"Can we go back a bit, though," Ryan asked. "How does some projection of your dog that you can't touch also have laser weapons?"
"Using the data mistress provided for me, I was able to process the energy used to maintain my holographic image into a heavily refracted image of light based on a photospheric construction, not dissimilar from-"
"Yea, alright, whatever," sighed Ryan.
"This act, however, has depleted my remaining energy reserves, mistress."
The Doctor nodded. "K-9, do you remember my sonic?"
"Of course, mistress. It is a very advanced screwdriver."
"Yeah, and a bit more. But, look, this is where I've kept your data. All those years, you've been right here. In my pocket. By my side. You're always with me."
K-9 paused, remaining quiet for an unusually long time. "Affirmative, mistress."
"I'm glad you know," the Doctor smiled. "See you soon."
K-9 gave one last bow of his head before disappearing once more.
"Doc, look at this," Graham commented, bending down to the rubble underneath the Witches.
One of the statues' feet had been knocked off, and was now lying under a pile of stone. On the base of the foot, however, were two thin circles that seemed to sparkle even though the light in the area was once again dim.
"No way!" the Doctor gushed. "Anti-grav stickers! I always wanted some of these."
Very carefully she peeled them from the sole of the Witch's foot and stuck them to her boots.
"They let you stick to any surface you walk on. The Witches probably wore them so that they didn't accidentally fall over and crush themselves. These are so cool!"
"You did just take something from the bottom of a Witch's foot," Graham reminded her.
"Not just anything; anti-grav, Graham!"
