Kinda shooting in the wind with the blond girl. Bulbapedia doesn't have an image to go by, but states that her facial features and hair resemble Serperior's, so I assume this is Mako from the latest movie.
She's from the Pokemon Black/White Movie. She has her gothorita squeeze some oran berries so a few children could enjoy some juice, while her gothita slices a couple of watmel berries for others to eat. Then she finally shows up to do a courtsey(am I spelling that right...?) with her pokemon.
