Anticipation of how Martinez will handle his cross-examination of Arias has been building since she took the witness stand on February 4.

Martinez is known for his feisty courtroom demeanor. Martinez has become frustrated with some of his own witnesses during the course of the trial. He has raised his voice on numerous occasions.

In Session host Vinnie Politan is a former prosecutor, and he says Martinez needs to walk a fine line when he's questioning Arias.

"I don't think Juan Martinez can control himself, and I don't think he will. We've seen it already. Do you have to be careful? If I was doing the cross-examination, I'd be a little careful about crossing the line, the line where she appears to be the victim, because that's the character she's trying to play on the stand. That is the story of the defense. That is the defense, she's a victim. So, on the one hand, you don't want to cross that line, but you want to get as close as you can to that line," said Politan.

Politan says Arias' answers to Martinez's questions don't really matter. What really matters is the content of Martinez's questions.

"The defendant is going to say whatever they're going to say. This isn't Perry Mason, they're not going to confess to murder on the witness stand. Your questions are basically you pointing out to the jury all the problems with her story, her theory and everything that she said. You ask leading questions, and you're allowed to, on cross-examination. Leading questions are questions that suggest an answer and the answer is either yes or no. You don't ask an open-ended question."
