"Who knows?" professor Oak answered with a shrug. "He stayed around for a while after his last duel with Red, but then he up and left. That was several months ago..." He scratched his chin. "I suspect he's gone off to train for a rematch. He had a bit of a revelation there, at the Indigo Plateau, and I wouldn't count him out of the game just yet. He's my grandson, after all." Oak folded his arms and nodded sagely to himself, then looked up. "But that's it for personal questions. I've got a lot of trainers to get to."
It wasn't long before everyone's registrations were finished, and the young trainers were ushered out of the lab. With a last reminder to read their pokédex manuals, the professor shut the door. Professor Oak's paddock lay empty, green fields still glistening with morning dew, distant sounds of people chatting and pokémon stirring making their way from around the building. Jack turned toward the other trainers and scratched his chin with the edge of his pokédex, then smiled.
"Okay then, without professor buzzkill around..." he said to himself, and with a flick of his wrist, his pokéball came rolling out of his sleeve and into his hand, "we can finally get to the good part." He threw the pokéball into the ground, where it bounced up, cracked open and released a small, green dinosaur onto the grass. Jack stooped down to pet it, while reviewing its page in the pokédex. "Green colour... you don't say? Footprints, blah blah, dietary needs, blah blah... ah-ha! Moveset! Oh, and, uh, hi there, little guy. You and I are gonna go far."
"Bulbasaur!" the pokémon cried happily in response, and Jack stood back up. "So, who wants to take us on? We're already falling behind those guys over there," he nodded toward the fighting on the other side of the lab, and Bulbasaur cried out again. With a quick gesture, he flipped his pokédex closed and stuck it in his pocket. "Off the record, of course. I can't afford to lose and go broke on my first day!" Jack grinned sheepishly, and Bulbasaur gave him a sour look at the vote of confidence.
