I had one volunteer... well, calling them a "volunteer" might not be the right word for it: an associate of mine accidentally contracted the disease while we were speaking with one of the townspeople, and he allowed me to take enough samples of the thorns growing from him to test on.

[Azul moves a few of his pages here before finding the right ones and taps them]

I documented every attempt in my notes here, so you'll be able to see everything I tried in order to find a way to prevent the thorns from growing back.
