can you have two characters talk at the same time and how?
Take a look at Character.SayBackground() (http://www.adventuregamestudio.co.uk/manual/Character.SayBackground.htm). Since it isn't blocking - unlike Character.Say() - you can use it to have more than one character speaing. It doesn't play the talking animation, however - if that's a problem there are work-arounds, or you might want to look at the BackgroundSpeech Module (http://www.adventuregamestudio.co.uk/yabb/index.php?topic=21715.0) which has done the work for you.
