As a fan of literature, television, film, animation, and comics with strong and vibrant female characters, whenever the DVDs/online episodes are available for viewing, I'll probably quit watching in disgust as soon as the events that you're referring to occur. I feel no compunction or desire to continue supporting a work when women characters are gotten rid of for no discernible reason.
