set Arshes as the starting party
set the start location where you want Arshes to be start
make an event on a blank spot that doesn't matter that much and set it to auto start
set a move event for Player that makes Arshes walk to where Gloria is (move right, move right, move up....)
put in a wait of a certain amount of frames equal to how long this move event takes and follow it with the messages you want to insert (do this thru guess and check by test playing)
then make a move event for one of them and copy it so you have 1 version of the move event set to Gloria and 1 do Player
hope that helps
at this point you can then put Erase Event
