I think he knows that. Every second edition scenario (other than the intro) uses one or more "open monster groups" (which are limited by symbols on the scenario/monster cards), so plenty of opportunities to use converted 1E monsters in 2E. It was a well thought out idea.
Yes, this is what I wanted to know. I do indeed know that the box comes with no plastic figures. I'm glad, because I have those already! I just wanted to make sure there was an easy way to get the old monsters into the new quests. Thanks.
