No, I mean he will have to wait a long time to hear it.... living dust whose life processes moves hundreds of thousands of times slower than organic chemical process will take a long time to say anything. I envision the conversation going like this:

Day 1
  Dusty: "Ugly..."
  Scientist: "Yes, yes?"
Day 2
  Dusty: "...bags..."
  Scientist: "Okay."
Day 3
  Dusty: "...of..."
  Scientist: "For the love of God, somebody shoot me!"
etc...
