...Aftran is the Yeerk who made Cassie think about Yeerks in a different way. Aftran made her realize that Yeerks are individuals, no two alike. She forced Cassie to accept that all Yeerks are not our enemies...

...Aftran, in the body of Karen, her little girl host, had tracked Cassie down, planning to turn her over to Visser Three. Long story short: Cassie saved her life. She saved Cassie's life. And then Aftran willingly returned to life as a blind, helpless slug-like creature. She sacrificed her freedom to free Karen...

...I am Illim. I control Mr. Tidwell. We are both part of the Yeerk peace movement...When I first entered Mr. Tidwell, I was not part of the peace movement...He was an involuntary host. No. That is too nice a way to say it. He was my host, my slave...It was partly experiencing Mr. Tidwell's distress that led me to join the movement...His howls of fury and agony forced me to accept what I had done to him. At the same time I began to hear about a group of Yeerks who thought it was wrong to take an unwilling host...

...I, Mr. Tidwell, invited Illim to stay in my body...I thought together we could do more for peace than he could do alone. He is within me now with my permission...I wanted to do something with my life. So I decided to join the fight. What could be more important?...

...Mr. Tidwell and Illim have a message for you from Aftran Nine Four Two...She has been taken by Yeerk security...Aftran is unharmed, for now. She hasn't been questioned yet...Visser Three wants to handle the interrogation personally...when the Visser finishes with Aftran, he will know everything. And then every Yeerk in the peace movement will be dead. Their hosts as well. Everyone who has ever helped you will be rounded up and made Controllers...Everyone you care about will be made Controllers. It will all end. The defeat will be total, and permanent...
