What happens in the last episode of Pokemon Diamond and Pearl?

At the last episode of Diamond and Pearl Ash and his crew stayed at Dawn's house until the afternoon. Dawn was planning to go with Ash but Dawn and Buneary had to go to the Pokemon Fashion thing. This made Priplup mad so it ran away and long story short they found Priplup. At the end Ash and Brock is about to leave Twinleaf and say their goodbyes to Dawn. At the very end Brock and Ash take their own road. Ash go for Pokemon Master and Brock go for Pokemon Doctor.
