I'm almost afraid to ask what the first event page is...
Personally, I never
use self-switches (mainly since there's only 4), and if I'm going to use the insidious autorun, I have it delete itself. And I typically never use double-event pages; that's for doors, which I let VX make for me (hassle).
Assuming this all starts when the guy walks in the room/house/whatever, have it as a "blank" (sprite-less) event hiding somewhere (in a wall or something, so it can't be found or accessed by the player), auto run the event the same way, then have it delete itself. It ensures that the autorun won't stop the "action" (since it's erased itself). You can also save the guy, so that if you missed some detail, you can talk to him again (sans autorun scene).
