Technically, only one.
Peeta tells Caesar that he killed Brutus in the 75th Hunger Games. This was his only direct kill.
Many people say that he killed Foxface too, but he didn't. Foxface died because she stole some poisonous berries from Peeta. Peeta hadn't fed them to her, he didn't even know that she had taken them until she died from eating them.
And in the 74th Hunger Games, Peeta just pretends that he killed the girl who lit the fire next to Katniss's tree. This was a lie to build the Careers' trust, so he could protect Katniss from them. The only reason the cannon didn't fire when Cato killed her, was because the Gamemakers were signalling that Katniss was treed next to them. Peeta went back to 'finish her off' but didn't do anything since she was already dead.
No
They are hoping that Peeta will lead them to Katniss so they can kill her.
That Peeta has teamed up with the Careers and is helping them find her and kill her.
because she will have to kill him
She doesn't get to see Peeta because Peeta wants to kill her. Peeta was kidnapped by the Capitol and they used trackerjacker venom to corrupt the images of Katniss in Peeta's head so that when he sees her, he will try to kill her.
No
They are hoping that Peeta will lead them to Katniss so they can kill her.
Peeta didn't really kill Foxface, or at least not intentionally. Both Peeta and Foxface didn't know that the berries they found were poisonous and Foxface saw Peeta grab some, so she assumed they were safe and she ate them. Peeta didn't eat them because Katniss told him that they were poisonous
Tributaries do not make a river, a tributary is a stream that flows into a larger stream of river or any other body of water
The Careers use Peeta to figure out what Katniss' skill was that got her the eleven from the Gamekeepers. The Careers also think that Peeta might know Katniss' whereabouts.
No, but he does TRY to kill her when he gets back by strangling her.
Cato is holding Peeta so if Cato dies Peeta dies
That Peeta has teamed up with the Careers and is helping them find her and kill her.
She means FoxFace was your target you were supposed to kill here
yes
The capitol trys to kill him but instead they erased his memory
They were using him to get to Katniss and then they were planning to kill him.
