I heard that in the manga Jessies and James are married and actually have a child, what is kind of disturbing, because I also heard that Jessie and James are only 6-years older than Ash in the Manga, and Ash doesn't age for some reason
i thought jesselina fell in love with james after he fell in love with her in season 1 but somethin happend between them so he joined team rocket i think she wanted him to get rid of growlie his growlith
Sorry, but I guess you got that wrong. When James says "We, big brother and big sister-" he means that both, Jesse and James, have younger siblings. The confusion of the three dudes is caused, because Jesse and James appear to be 15 years old but Meoth says something about that they are making out. What Jesse says in the beginning is directed to the hero crew.
