FF6 ROTDS first time run playthrough

Ah shit, that still won't do it cause then you could just leave again and remove Aurora and the guard will be gone... Hmm what to do what to do. I guess move or create another event trigger at the start of the Sealed Gate cave entrance.

EDIT: Can edit the event there that removes the guard to be:
If certain event bit is set AND if she is in the party, then he is hidden. If she is not then he is there. Again, seems very strange since they are trying to lure her into the damn place, but ah well. Either that or block the chocobo from walking across bridges or something...or add another block chocobo tile around there.
I like the guard though, he can just be there and according to RPG logic it won't have to make since why he appears and disappears if she is/isn't in the party. Unless you or someone else has another idea, I'm all ears.
