XD I just got creative to the extreme. The following idea is totally random...
It's five years later, and Bianca was the one who revived them, because her grandfather died. She lets them back into the garden, telling them to never leave. She desperatley tries to get a hold of Ash, but ends up meeting a twenty year old Richie, who then sets out to find Ash, and then Ash goes back and meets Bianca. Ash is now a Pokemon Master, so he can only stay with Bianca for a few days.
But Team Rocket used the combined efforts of Jessie, James, Butch, Cassidy, Annie, and Oakley to try to again get the Lati's. Jessie and James have taken the place of Giovanni at the Team Rocket base, and Meowth has set out on a journey to capture his own Pikachu. (^-^)
Then Bianca fights back, nearly getting herself killed by using the Defense System thing, and blows Team Rocket into the sky. Then the Lati's live in peace and Ash invites Bianca to come back to Ever Grande City with him. She turns him down, then quickly runs away, crying. Ash is about to climb onto the boat when Bianca runs out, handng him a picture. Ash unfolds it, and it is a picture of Ash as he is now, with Bianca standing next to him. He looks up and Bianca (NOT Latias) kisses him.
Teh End.
