Oh yeah, the Luxord line and the "???" line are actually the exact same ("The game isn't over until it's over") in the localization. But I'm not sure there's really a connection there.....
(I checked [most] of Luxord's and Brain's lines but haven't found any really similar lines, besides that one line where Luxord mentions chess...but I don't think that one has anything to do with anything. But I gotta say, they both definitely have similar characteristics....)
Hmmm...but the translations have to go through multiple checks before being approved. Lines like this that aren't in the original Japanese can't be just random lines out of the blue.....right?? ?

HMMMMMMM!!!!!
WONDER WHAT HE'S UP TO THERE THEN. I MEAN, BESIDES KILLING CHAOS OF COURSE
