Bonnie has been the most genuine character this season. She's also been the funniest. The XY cast would be dead without her.
Opinions, man: opinions- we all have them.
You're free to like Bonnie or anyone, but not all of us do, of course- I don't find her funny at all and I think, if she was either handled better more often like in "Flabebe and the Fairy Flower," or not even in the XY cast, it would be better.
