From Richard Greene in the courtroom: Pistorius and some of his lawyers are passing notes back and forth.
Johnson and Burger's cell phone records indicate that they called security at 3:17 a.m.
Roux points out that at 3:19 a.m. Pistorius called Mr. Stander for help, and that this was shortly after he'd broken down the door, which would mean the sounds the couple heard was from a cricket bat not a gun.
Roux: You can say as you sit there that those noises didn't come from someone taking a cricket bat to the door.
Johnson: I'm certain I heard gun shots, I'm familiar with the sound.
Roux now asking if Johnson is certain he heard gun shots. Back to the cricket bat versus door debate.
Roux: You also believed that what happened at that house (an assumption of course) was that they shot the husband. And that would be not because it was the screaming of a woman that was threatened, but because she was fearful for the safety of her husband.
Roux has moved on to Johnson's assumption that the commotion they heard was a break-in and not domestic violence. "We're exposed to violence," Roux says. Johnson agrees.
Roux painstakingly going through every element of Johnson's statement. They're now running through the timing of events again.
Roux is saying that because Johnson testified that he thought there'd be other people who heard more clearly, he didn't hear clearly. Johnson disagrees.
Roux now questioning Johnson on the time between the screaming and the shots. Johnson cannot put a time duration on it. Says it didn't feel like long but can't give specifics.
Roux to Johnson: You and your wife could just as well have stood together in the witness box.
Johnson: I can honestly tell you we did not discuss her testimony.
Roux: Once witnesses start to introduce with honesty, I start to worry. They should've been honest from the beginning.
Johnson: Witnesses should come to court uncontaminated and give independent testimony.
Roux has Johnson on the ropes. Johnson said previously that they hadn't discussed their evidence of the case together, but now he says they did discuss how many shots they heard and the timing of them.
Roux: Mr. Johnson maybe I must stop you, you don't know what you're doing to yourself.
Johnson says he did see his wife after she testified and before he testified.
Roux seems to be suggesting that Michelle Burger and her husband Charl Johnson discussed their testimony while waiting for Johnson to be called to testify.
Roux: Neither statement mentioned a pause between the first and second shots, but both testified to that. Johnson says it's not a coincidence if both people experienced a similar event.
Roux about the similarities: It's about the exact same word - not in your statements, but in her testimony. It may be a remarkable coincidence, but there are six of them now.
Johnson says he's satisfied with his explanation.
Roux continues to point out the similarities between both statements and testimony.
Roux brings up that during testimony yesterday, Johnson said he heard screams intensifying - the same as his wife. Roux also points out that neither of them mentioned that fact in their statement. Johnson says it's because telling the story verbally is more emotional.
Johnson explains that he made notes on his computer about what had happened that night. He made the notes before he gave the statement to Captain van Aardt. Some of the details in the notes were not included in his official statement. The notes are now on his iPad in the witness room. Roux would like to see the notes.
Roux is now comparing Johnson and Michelle Burger's statements to what they've both testified to so far.
Johnson explains that him and his wife are highly routine-based people.
Roux: What was interesting about your evidence yesterday, is that you say that you went to be between 9 and 10 p.m. What was interesting was that in your statement you said you went to be at approximately 9 p.m. Your wife testified that you went to bed between 9 and 10.
Roux has given Johnson a copy of his statement, they start going through it.
Johnson says he hasn't read his wife's statement and that he hasn't discussed it with her at all.
There's been a disturbance in court. Seems to have been a telephone. She reprimands someone in the gallery and asks for phones to be switched off.
Roux asks Johnson where he was when his wife was testifying and if he discussed the case with his wife. Johnson says the two of them did not discuss what they were telling the court.
With that, Nel ends his questioning and Roux begins cross-examination.
Johnson turned his phone off. When he turned it back on he had a voice message that was of a threatening nature. Johnson feels that his privacy has been "compromised severely."
Gerrie Nel asks Charl Johnson if he is aware that his cell phone number was read out in court. Johnson said his phone "started ringing incessantly" during the morning session of court.
Judge Masipa has arrived, court is back in session.
We should be underway shortly. Charl Johnson, who lives near Oscar Pistorius, returns to the witness box. State advocate Gerrie Nel will continue direct examination.
15 minutes until court resumes for day three.
