((Coming from
here. ))
The woman's wing meeting room was right next to the Xigbar's wing, right? So as Xigbar dashed into the bathroom, he made the calculation that if he just teleported through the wall of the bathroom, he'd be able to get there right away and at least see if Luxord had any, er, 'discolorations' on his face to take care of before the meeting started.
Kingdom Hearts knew that they'd need as few distractions as possible if they were going to get through this.
So, dashing to one stall and nodding, he hopped through...
...and promptly miscalculated, sending him to the wrong men's hallway.
((And he gets dumped
here. ))
