"Lately it occurs to me that there is no defense against human stubbornness. I have watched the elf live for decades, far beyond reason. Long after death should have come, even after becoming a twisted thing, the elf persevered, and I do not know why. Meanwhile, your companion committed to a path of suicidal hostility, despite all evidence that I was willing to exercise restraint. The elf seeks life still in the midst of death, and the ape seeks death in mercy's stead."
"People will commit to any action, no matter how foolish or futile, and keep to it beyond all reason. I do not know what in your nature makes you prone to insanity, but I do not like it so close to my home. Unfortunately, as long as there are things in this place that people want, people will keep coming. As long as people keep coming, there can be no stability in my home. Bugs. No bugs. Drones, security doors, gas, bombs, shock traps, none of this will keep people from things that they want. Therefore the most logical action is to take the things that people want and remove them. I would offer you future assistance in exchange for helping me with this."
