Two weeks after Alexander's death, everything was back to normal for most members of Organization XIII, Bob was released, though in truth, he still wanted Alexander to come back, and hated both Luxord and Sora for it. That was when Bob got a mission from Saïx, covering the one thing that Bob wanted more than anything else in the worlds, payback.
"Are you sure you can handle it? If I am correct, you have no weapon?" Saïx asked.
"Oh, I can handle it plenty by myself. I could very well KILL Sora with just one thought, and that's what I'll do." Bob chuckled. "Now buzz off beserker breath." Bob then fired off insult after insult in an attempt to upset Saïx.
It must have been that time of the month, and Saïx went beserk, and Bob just walked away casually, as if nothing went amiss. "Heh... I've wanted this to happen for so long... and I finally have my chance to shine!" He laughed maniacally, as if he had been locked away in an asylum for fifty years, and headed out of the Castle that Never Was to find Sora. Bob's insanity would ironically turn out to be his own downfall.
Two hours later...
"Oh boy... well, I never thought I'd be so close to winning and then lose to you... I was wrong, wasn't I? Heh..." Bob smiled weakly, then collasping, with each word he said he shivered, as if from cold. "Ahaheheheh..."
Sora had almost mortally wounded Bob.
Bob looked up at Sora, "I can finally reunite with Alexander... if you spare my life, I'll kill you, I'll kill..." Bob started, before the slow whir of a machine slowly died down. "...Everyone you love..."
"I'll spare your life, but fight me again, and I'll have no hesitation killing you." And with that, Sora walked away.
"Heh... I'm going, I'm going..." Bob muttered, standing up slowly, creating a portal back to the Organization, and limped through. "I'll be back... and when I am, Sora, I'll..." He never got to finish his sentence, as Saïx, who was still going beserk, punched Bob in the back of the head, knocking him out.
I wonder what's happened to Bob? We'll find out someday, won't we?
