David rolled his eyes at the rude but obviously stressed professor. "Yea yea old man." he sat watching the new trainers and looked seeing jimmy. he walked over and said "Hey Jim...its been awhile....has youre pokemon gotten any stronger?" He smiled and watched as the mentor came in and handed everyone a pokeball. he decided to be night and said "hey guys take these." He handed the trainers each a potion. 

he watched the trainers battle. Both water pokemon were certainly strong. He smiles seeing the Totodile's stategy. But he had to be careful, that could cost him the battle. he clapped when the battle was over. "Good job guys." He said getting down and petting both pokemon. He fed piplup a revive. David stood up and said "I can tell both youre pokemon are going to be powerful. You two will also get stronger. Its up to you two to believe in each other though." David smiles at both.

He then went to Flora and asked him. "So when did this mentor thing start? It wasnt around when I started my journey." he then had a idea. "why dont we have a battle? im sure you have some pokemon on you." David smiles.
