Latias & Latios

Latios and Latias are brother and sisters. In the movie "Pokemon Heroes Latias & Latios" I'm only going to tell a few parts. Ash and his friends are in some kind of town (I forgot the name i'll put the name on when i know how to spell it) Anyway. Ash runs into this girl which is really latias. After ash saves latias. Latias starts to have a crush on ash. Thats all i'm gonna say. If you know what happens then just tell me you know.
