[@Ardent Dawn] I'm calling this now. We have a group whose explicit goal seems to be to take out the Legendaries. The Power Plague had the greatest effect on powerful Pokemon. Who are the most powerful Pokemon? Legendaries. Didn't work, so now it's time for a more direct approach. 

Hope was pulling her little speech out of her butt. The fact that she was actually right seems to be a coincidence. Which makes it even more of a shame that we may not see her again.
