Code I used

// Gurad Xor
// follow
if (player.hasReadDialog(33)) {
 npc.getRole().setOwner(player);
 npc.getRole().setInfiniteDays(true);
 npc.getRole().addDaysLeft(1000);
 npc.executeCommand("/noppes dialog unread @p 33");
 // stay
} else if (player.hasReadDialog(34)) {
 npc.executeCommand("/noppes dialog unread @p 34");
 npc.setReturnToHome(false);
 npc.getRole().setInfiniteDays(false);
 npc.getRole().addDaysLeft(-2000);
 // return to post
}  else if (player.hasReadDialog(35)) {
 npc.executeCommand("/noppes dialog unread @p 35");
  npc.getRole().setInfiniteDays(false);
 npc.getRole().addDaysLeft(-2000);
npc.setReturnToHome(true);
}
