Since FFIII isn't an RPG with a whole lot of unique NPC chatter, he'll say the exact same thing he did before...and also jump three or four more spaces to the right. Do this a few times and he'll have jumped beyond the boundaries of his house, writhing in inky limbo. Now you have Granny all to yourself.
