I mentally breathed out another sigh of relief as I thanked my lucky stars that I remembered to teach these guys some basic biology. "Yes, they're pretty much just single cells that just so happened to be able to invade and destroy other cells."
"Oh..."
"I won't bother with the rest since it won't be relevant anyway," I lied as I erased even more details from the board and focused on the one structure that we can interact with. "This cell wall is what we have to destroy so that we can kill it."
At least, that's how I remembered it working. How alcohol killed these things was beyond me, but I could only assume that it being painful on open wounds had something to do with it.
"So how do we kill it?" she asked.
