I played Rogue Galaxy once, and this part I was at had just the main character, Jasper, and some random lady with you. I went exploring and fighting stuff, and the NPC teammate with me kept yelling "Jasper!" over and over again with a little variation. Seriously, it got to be like this:
"Jasper! Jasper! Jasper. Jasper? Jasper! Jasper!"
I stopped playing because holy crap did that get annoying fast.
