Ugh. Taking people over. Never a good way to go. Ever. "Infectious parasite type?" Ew ew ew. "Hive mind I take it? Something that could coordinate?" Because one couldn't normally stuff enough brains for independent thought in something like a slug.

"How long ago?" Better to know. And even more importantly..."Any likelihood of return? Should I keep an eye out for them?" Because...true monsters rarely stayed dead.

Especially infectious kinds.
