"She can talk?" William thought, and was stunned enough to forget about the wound on his ankle.
Even though he had seen blue-snakes talking before, he was still shocked, as these creatures could only bee seen going berserk. To have one of them speak softly, felt like a ground-breaking discovery!
Things got a lot more confusing, when the same creature said. "I can do more than that, demon. But I do understand why you'd assume my intelligence as... inadequate. There aren't so many talking fish around here."
The most bizarre detail out of that answer, was that William didn't speak at all through these few seconds, yet this blue-snake specifically answered to him! Such a gesture broke quite a few secretive, and certainly personal protective walls, so he had to work around it.
Instinctively he summoned the IQ estimator, just to get a decent grasp of what they were dealing with.
