Where his voice was low and slow, it now bounces and is tinged with hope, growing happiness.
Where once he was haunted, he is now healing.
Hisham still has his moments - days where the flashbacks are too real, the pain too great and the fear and anxiety is cloying.
But he's ready to face the anniversary of the terror attack and begin the next, and hopefully best, chapter of his life.
The beginning
Hisham was shot three times on March 15.
The bullets tore through his hip and he fell to the floor.
Bodies piled on top of him and all he could do was lie there, trying to be still and silent, terrified the gunman would come back and finish him.
When the shooting stopped, he managed to wriggle free, and saw his friend beside him.
"I started crying and trying to help him, I held his hand… I said 'you're going to be okay'.
"Khaled was smiling - as he always smiled - and I thought he had taken his last breath.
"I realised I could not help him… then I looked for other people that needed help… I remember that feeling."
Hisham and Khaled were both born and raised in Syria near the capital Damascus, but did not meet until after they had both fled with their families to Jordan.
They forged a strong friendship - as did their wives Susan and Salwa - and when the two families were offered a chance to come to New Zealand as refugees, they did not hesitate.
They settled in Christchurch and were so happy to be here.
Their children started school, their wives started to study English, the men got jobs to support their families.
Khaled worked as a farrier and Hisham as a plasterer - though, holding a masters degree in geography and working as a teacher for years in Syria, he had bigger plans for his future.
The men spoke every day, at least half an hour on the phone, about their lives.
"Every two or three days he came to my house and we drank coffee, we sat together and talked," Hisham said.
"Every Friday he would come and take me to the mosque, I went with him and his family … Every Friday."
"We went together to the mosque, we walked in the front door together and we sat together to pray - there was only 1m between us.
"After about five minutes we heard the first three or four bullets.
"We did not know what it was, we thought it was someone playing a game … We looked to the front door and we could see bullets coming everywhere … He was shooting the walls, the roof, then the people started to run …"
Somehow, despite his injuries, Hisham could still walk.
He stumbled out of the mosque and called Susan.
He knew word of the shooting would spread quickly - and he did not want her fretting.
Back then, Hisham could not stop replaying the massacre in his head.
He lay under the bodies of his brothers for just 17 minutes, but it felt like a lifetime.
"That 17 minutes was unbelievable … I don't know how I could survive," he said.
"It was a very hard 17 minutes."
Later, lying in his hospital bed was trying to make sense of it, to see if he could find his friends in the fracas, to work out who had lived and who had died.
Physically, Hisham's condition was serious - doctors removed some but not all of the bullets.
He wasn't sleeping much because of the pain - in spite of the array of prescription meds he was taking.
"Last night was the first night I slept well … before that I would only get three or four hours sleep," he said.
"It's hard, I get grumpy."
Hisham had other battles raging, too. Emotionally and mentally, he was not coping well, and he was desperate for his parents to come to New Zealand to support him.
After they fled Syria they settled in United Arab Emirates and, because of complications with paperwork, they were not able to come here immediately to support their wounded son.
That meant Susan bore the brunt of everything on her own.
On top of looking after Hisham, she was also was dealing with three young children, running the home, being there for Salwa and running herself ragged trying to hold everything and everyone together.
"It is hard to see the other victims with their families … my wife is very alone, I am very alone, isolated," Hisham said in May.
"The community has helped us, but it would be good to have our family in our home with us.
"My health, my mental health, it's so bad I just want them to help me … It has been a very hard few months," he said.
By May, things were getting "a little bit easier" and Hisham did everything he could to stay busy, to keep his mind occupied, to not think about the attack.
"I can't keep thinking about what happened … I try to be busy, I try not to be in the position where my mind thinks about it," he said.
"Of course, this will be with us for the rest of our lives - we just need to work out how we deal with it in our own way.
"For the next few months I just want to focus on my family … taking it slowly."
By October, things had taken a good turn.
When the Herald visited, Hisham's mother was in the kitchen with Susan and the older children making traditional Syrian food - the intoxicating scent filling the house.
Hisham's parents and brother had been approved to visit New Zealand for three months and he said it had made a huge difference.
"At last, they came … I was very emotional when they arrived. It was very, very nice and hard at the same time," he said.
"At first they did not ask but then yes, they had questions. It was helpful for me to talk about what happened. My family know their son and they know how they can deal with him."
Hisham still could not work and he was getting frustrated.
Financially, it was not easy. But sitting all day, unable to be productive or contribute to his family was doing his head in.
He wanted to at least volunteer, to get out of the house and make something of his day.
But the lingering nerve pain made that almost impossible.
"At some stage, maybe there will be no pain? But maybe it will stay forever," he lamented.
She has a broad smile on her face as she greets, welcomes, calls to Hisham who is out the back of the house.
He strolls in, barely a limp, and sits down in the lounge.
The kids are watching videos on YouTube, sucking on lollipops on the lazy Sunday morning.
Hisham grins at them, especially Roua who turns 2 on March 13.
She's grown a lot since the Herald first met the family, and she's becoming quite the independent little character - her deep brown eyes showing the unmistakable spark of sass and mischief.
They are good kids, and they know how to help their dad.
Rena is the only one who has asked about what happened.
Initially they told the children their father had been in a car accident. Hisham and Susan wanted to shield them from the truth.
"We explained a little bit to Rena, but I don't need the children to think about this at this age - they are children, they should think that life is normal and easy and fun," Hisham said.
By and large, the Alzarzour kids have not really been affected by March 15.
And their parents are slowly starting to unravel the damage done.
Hisham says a huge part of his own healing has been because his family were able to stay in Christchurch.
They are in the midst of a residency application and, in the past few weeks, have moved into their own home in Ilam.
Hisham's brother has a one-year work visa, allowing the talented engineer to apply for any jobs he can find.
His father is an experienced crane operator and, once he is granted residency, he is told he will have no issue getting work in and around the Garden City.
Having them here, knowing they can stay, has lifted a huge weight of Hisham.
"Until they came, my wife did everything and it was hard for her," he said.
"She was telling me recently how it affected her - her feelings most of the time were anger, sadness, depression.
"When I had pain, she worried. When I had mental health issues, she worried.
"Before this happened I would play with the children, talk to my wife all the time - but after I didn't do that, I didn't spend time with my family, I sat alone …
"I wanted to be alone, I say by myself just thinking how I was so very sad and angry."
Things are still up and down but, increasingly, Hisham is feeling better.
Every week day he and Susan attend an English language course.
Two or three times a week he volunteers with the City Mission.
In terms of the anniversary, Hisham and Susan will go to the memorial on March 15 with his parents.
"It will hurt, but it's good to remember the people we lost," Hisham said.
"March 13, at the mosque will be more important for us - it is Friday prayer, so really the anniversary of what happened at that special place.
"It is Roua's birthday that day, but we will probably do something before - she will lose that day this year."
One of the biggest changes for Hisham is feeling safe again.
He says he will never truly let his guard down, but he is now comfortable in his own home again, satisfied his wife and kids will unlikley be harmed there.
The days he would sit in silence, the nights he would not sleep, the hours he would spend away from the house in a bid to keep busy and not let himself rest for fear of the thoughts that would creep in.
It was exhausting keeping an eye on him, trying to be what he needed and be ready to react to any and all of his suffering.
"Emotionally, my wife is stronger than me," Hisham says, glancing over at his bride.
"I have to be," Susan replied, matter of factly.
"There is a saying, if it does not kill you, it makes you stronger … I am so much stronger, I can deal with anything now."
As a couple and as a family they are also stronger and closer.
They are looking forward to their future - which will be in New Zealand - and working towards their dreams.
"When I think that it's been a year since the attack, I think I've gone crazy because I remember it like it was yesterday," Hisham said.
"Now, we just want to get past the anniversary and have a quiet life, a normal life.
"We just want everyone to be peaceful, like before."
