Just as a pointer, to erase a graphic you could have instead of doing that way, change the graphic in the move-event command window, it is on last row, 5th command from the bottom "Change Graphic..." and set it to nothing, or a blank setting which would render the king invisible. Giving the same illusion of him leaving that you did without having to switch the events.
Just another way of achieving the same effect if anyone was wondering otherwise. Eventually I will work on my own text and picture tutorial for cutscenes, it is already started. I'm going to go into other aspects of cutscenes, some of which were shown here but others may not have been.
Overall a good tutorial on the basics of cutscenes, keep up the good work.
