Ender and his army have just finished practicing and Petra comes to talk to Ender.
Ender, we need to talk. It's about Bonzo. He wants to fight you and win.
What? What are you saying Petra? He wants to kill me?
Ender and Petra keep talking about the future situation, but Petra just tells him to be careful.
I don't know all the details, but just be safe and be aware. I gotta go.
Ender is speaking to himself (consciously) and warning Bonzo in his head that he's more dangerous than he seems.
If Bonzo wants to play with fire, he's gonna get a whole explosion if he thinks I can't beat him.
"Ho, Ender!" someone called. Ender stopped and looked back. It was Petra. "Ender, can I talk to you?" (204). This quote is setting up the basis of Petra telling Ender about what would happen to him at some point.
Dink has left a message for Ender, warning him.
(Sighs) Oh, Dink.
Look Bonzo, I don't know why you have such a bone to pick with me, but it ends right here and right now.
"Ender, they can do it. He said they've been planning it ever since you went commander--" (204). This quote is just about Petra telling Ender what has been going on ever since he beat Salamander Army, in his opinion. She just wants to be a good friend and warn him.
Ender confronts Bonzo because of the growing issue that they need to handle.
Ender, you should know why I want to hurt you so bad. You are nothing to me. You're dust and I'm superior.
"Use what they give you," Ender said. "If you've ever got an advantage over the enemy, use it" (207). This quote is showing that Ender believes in himself and knows that he can beat Bonzo. He has the ability and techniques, especially the brains. He is better than Bonzo.
Ender has beaten Bonzo, after Bonzo thought that he was going to beat Ender. This is because Bonzo thought just because he's bigger, he thought he could beat Ender at his own game.
I told you not to mess with me, and now you've paid the price. You'll never learn, Sir.
"Don't be alone. Ever. -Dink" (205) This quote states that Dink wanted Ender to stay safe and always be careful.
Dear Ender, my dear friend, please be careful and know what you're doing. Be safe. -Dink Meeker
"Your father would be proud of you... Oh, what honor... You can go home and tell [him]... I only had six of my friends to help me... even though he was naked and wet and alone," (208-209) This quote is stating that Ender is thinking about what it would be like if he showed everyone that he can't be messed with.
"Ender Wiggin isn't a killer. He just wins – thoroughly” (226). This quote is stating that Ender isn't what everyone thinks he is, he just knows how to take care of his business.
