I was initially going to have Comet Girl stay dead. I was eventually convinced to have her return to life, but I was going to have her remain de-powered permanently. Eventually, a storyline came up where it made sense for her to return, but she's changed a great deal. Her power source is different. Her mindset is also changed.
