The real explaination is that Sparrow was going to be Pulse's first enemy. Instead of what really happened, Sparrow would steal a suit (thinking it was the only one) in the second comic. They would fight it out in the third.
I changed my mind, but had already set up odd events in the first comic. This was one way to go without erasing older pages.
I wasn't planning on giving a lot of information about her now, but maybe I should put in a few pages of explaination. It's just that in the past people have said I explain things too deeply.
