The Dink Network

I want a flashback to happen when Dink talks to a NPC. Kinda like this:

void talk(void)
{
say_stop("Hello , 1);
wait(200);
say_stop("`2Hello to you. Wanna hear my story?" , &current_sprite);
wait(200);
say_Stop("No." , 1);
wait(200);
say_stop("`2Well, I'll tell you anyway." , &current_sprite);
fade_down();
freeze(1);
sp_nodraw(1, 1);
*cutscene here*

I want the cutscene to appear on another screen to simulate a flashback. So it fades down and then fades up on another screen. What command do I use to accomplish that? I've tried draw_screen after the screen fades in the code but it just messes up.
