Australian terrorist Brenton Tarrant has shown clear signs of emotion as he awaits sentencing for the Christchurch mosque shootings he carried out last year.
A procession of his victims have presented heartbreaking testimony to the High Court this week, describing the loss of their loved ones and their still-raw traumas.
Several said they still have trouble getting to sleep, more than a year after the attack which cost the lives of 51 people.
Many described ongoing financial difficulties, trouble socialising and of course, the grief of losing husbands and wives, brothers and sisters, sons and daughters, and friends.
Very few elicited emotion from Tarrant, sitting roughly five metres away in the dock.
That was until Zahid Ismail took his place in court on Tuesday, standing stoically and eyeballing Tarrant while his pre-recorded video played on large screens in the court.
Mr Ismail lost his twin brother Junaid, who died of a gunshot wound to the chest at Al Noor mosque.
"While my pregnant wife and I were parking, a shooting was coming into reality," he said.
"My brother is now not able to see his children grow and see their development into adulthood."
Mr Ismail then described Junaid's "passion for cricket and pride in his long beard".
Tarrant turned his gaze from the screen and looked towards Mr Ismail, chuckling in acknowledgement.
Mr Ismail, his nose flared and his cheeks pulsing in and out, increased the intensity of his stare.
"I wanted to see if there was any empathy," he told AAP outside court.
"There is definitely a human being in there."
Later in the day, Nathan Smith - who was present at Al Noor during the attack - also drew a snigger from Tarrant when he suggested he should read the Quran "when you get a free minute, which you will have plenty of".
Mr Smith said he lived with the guilt of surviving the attack every day.
"After you left Mosque Al-Noor I was surrounded by people ... I held a three-year-old boy in my arms, praying that he was still alive. He was not," he said.
"Since the attack I don't sleep well and don't trust people. You have changed my life forever and I will never forgive you."
Despite the confronting testimony, for much of the sentencing, Tarrant has sat largely still.
Sometimes the 29-year-old would rest his hand on the desk, tapping one finger repeatedly while the rest of his cross-legged body remained motionless.
The terrorist is not inattentive.
He has maintained his gaze on speakers during their statements, or the large screens when pre-recorded statements play, occasionally nodding to victims as they finish their statements.
Mr Ismail was followed by his sister, Raesha Ismail, who described her non-Muslim community's embrace of her Islamic faith in the wake of the attack.
"After the events of March 15 I don't think I have to hide my faith in the workplace. This has been positive," she said.
"I've put up a Muslim calendar at work ... I was asked to host an Eid party which was well attended.
"I have strengthened my voice to be able to speak up for when it matters."
Both Mr and Mrs Ismail displayed the defiance that has characterised so many of the victims through the court this week.
Mr Ismail told AAP his testimony was "a healing moment".
"My (brother's children) will become confident, proud Kiwis that live in the same place as their daddy lived," he said.
"My family and I have always been strong individuals. I continue to attend (Al Noor mosque) and pray with passion and strength."
