I think we can all agree that Merryweather is probably the most cantankerous of the three fairies. She is abrasive and is often given to fits of complaining. When Flora first has the idea for them to sacrifice their powers in order to protect the princess, MW does everything in her power to not be a part of it. I don’t blame her though. With a personality like that, magic was probably the only thing that would make people want to be around her. But I digress.
Then, after nearly two decades of not using magic when they had almost beaten Maleficent’s curse Merryweather chooses to strike. It’s only one more day, but that is one day too long for the sprite. The day before the curse is moot, the three ladies all try to do their assigned duties: making a cake, creating a dress, etc without using magic. (I do question why these duties are assigned to these three instead of the King’s kitchen staff or tailors. And after 16 years, how these women couldn’t have figured out how to bake a cake…what did they do that whole time?)
Anyway, when they fail, while not overly excited about it, they all decide it will be ok…everyone except Merryweather. She cajoles the two other fairies to break out their wands to make everything better. This is bad enough, but she then proceeds to get into a magic battle because she wants the dress to be blue. Really? Is it that big a deal? Is it worth it after sacrificing for so long? This selfishness is what leads to the crow finding their location and everything going south. Now, should we let her off the hook because she helps solve the problem that she created by helping Prince Phillip save the day? I don’t think so. At minimum she should have her wand impounded and have a few years of community service…well, maybe just probation then with the 16 years of being an ordinary human being considered time served.
