Walter remembered a very similar scenario; asking what Murder Chicken was and being told they were a Murder Chicken, only for Murder Chicken to glance at their trainer, then turn to him and announce themselves. He smiled at them.
"It's hard to believe they were so small. Do you have any other Pokemon?" Walter always kept at least one out of their pokeball with him at all times (normally Assumption or Darkness), so seeing Krieg with his Pokemon didn't surprise him.

Assumption grinned at Torch Dragon. He was so shiny, like Wolf! "I like your colour! It's like gold. And your tail is all warm!" The flame from his tail made him seem even more shiny. How pretty!
