Edit: changed her appearance a little so that it is more consistent with the anime.
Edit2: Revealed that she 'keeps' her brother's Pokémon, and wants a sister-in-law.
Who knows, Bonnie is a character of many ambitions. But yes I'm pretty sure it's going to be a running gag.
Anyways, I came across this fanart, I thought you might be interested(if you haven't seen it already) : i1.pixiv.net/img121/img/bansok…
It is drawn by an artist on Pixiv. Be sure to respect her art.
Haha yes. I bet if you were in the Pokémon anime, Bonnie will want you to marry her brother for sure! XD this is gonna be hilarious. But I can imagine that Clemont will be really embarrassed >.< . And don't worry about becoming a psycho Clemont fangirl, I'm already a rabid Iris fangirl as it is! XD Every character needs people like us.
Oh and thank you :3
