Once everybody has reached the lab, they would see a few scientists readin books here and there, whilst a short round woman with ginger hair sits at a console, pressing buttons. As you apprpach, she is startled, but regains her composure quickly. Everyone here must be on edge.
"Oh, uh.... Hi there.... My name's... uh, Professor Chestnut! But.... uh..... you can just call me the Professor. I know why you're here, and you know why I'm here. If you don't..... well, uh..... too bad. Now, your PokéDexes are on the table over there. She motions to a table at the back of the lab. "So.... yeah. Get to it. There's also some Pokéballs, and some potions for each of you. Just warning you, you may want to team up, as the Pokémon here are quite vicious. Get into..... I don't know..... teams of three? Anyone left can go alone. Not my responsibility. Any more in one group and you'll attract too much attention."
Upon seeing Celebi, she lets out a slight gasp.
"OH! Is..... Is that really Celebi? The legendary Pokémon? No way..... that's so cool! You've got to tell me how you met it, and how you caught it."
You all gain:
3 Pokéballs
3 Potions
1 PokéDex
Now that you have your PokéDex, you can begin your journey.... But you may want to group together, as the dangers here are not to be scoffed at! But who am I to judge your strength. Maybe you feel tough enough to go it alone, but if that is so.... well, just don't say I didn't warn you.
