Katara almost said no, since it had been talked about and gone through her head and everyone preferred to think of her group as "the bad guys," but she thought better of it. She owed people like Will, who knew next to nothing about it, an explanation as to what was going on in her head.

"The long and short about it was the Yeerk are aliens with the ability to go into people's brains and pose as them. They've done it on the ship before, and while most of them are gone, there was this last one left. It had a trial to decide its fate, and it was decided it should be allowed to live. At this point, there were three kinds if people: those that didn't really care/agreed/disagreed and wouldn't do anything about it, those that wanted it to die and would go out of their way to make sure it was killed, and those who supported the trail's decision and would defend the Yeerk to the death. I was in the second category. I've been close to manipulated like that before."

There was WAY more to the story, but that was the bare bones for now.
