KAZAF'S PROFILE

Latly I've been working on the game I'm making. However I'm kinda stuck. You see I want the hero to walk into the castle and when he steps on a certain spot I want the person who is talking to the prince move down to meet the hero at the door than walk up with the hero following him than I want him to leave so it's just the prince and hero. I tried doing it, but the hero moved, not the guy.

Another problem I'm having is when he leaves I want the prince and hero to talk and while they talk a flashback happens, but I'm not sure how to do that without using teleport. And in the flashback again someone is suppose to walk towards the hero and when they are done talking disappear. And again, I can't get it right.

So you can anyone help me?
