Not the first time that have happened.the recent episode has convinced me they're struggling with the girls.
Even with Misty, the writers struggled, and eventually had to write-off her from the main story.
But, the 3rd and 4th Gen did help somewhat with the plot aspect for the girls (because of "Contest" for May and Dawn).
Then they went back to the old aspect, with Iris (which went even worse than Misty's time).
They also struggled with Serena for nearly half of the course of XY Saga, and introduced the "Showcase" to somewhat mitigate that problem, but didn't really help much (since she had a late start and early finish).
Bonnie being young, and the way she interacted with others made up for her presence. Plus she didn't really need any plot for handling, but the writers still game her good amount of interaction (even better than Serena). If i have to say, Bonnie until now has been the best handled female character in the show.
But in SM, they not only have one, but 3 girls to handle around. So, its going to be much harder than before.
