'No, mum said she just wanted it to be the five of them,' he said.
'She wanted to talk about personal stuff.'
Patterson said her son was incorrect.

Dr Nanette Rogers suggested Patterson didn't want her kids anywhere near the lunch because she knew she'd be serving up a toxic meal.
'Incorrect,' Patterson said.

Prosecution: 'I suggest this is a story you made up'
Patterson was reminded about evidence she gave where she went foraging for mushrooms with her children.
'I think they even found a couple [of mushrooms] for me at one point,' Patterson previously told the jury.
Dr Rogers reminded Patterson of her son's evidence where he said he'd never been foraging or searching for mushrooms with his mum or dad.
The son said he remembered seeing mushrooms growing while on walks with his mum and sister in 2020 and 2021 but didn't remember picking any.
The son said his mum took a photo of a wild mushroom but he said 'he never knew' his mum to go foraging or picking wild mushrooms.
Patterson's daughter also said she'd never gone picking mushrooms and had never seen one while with her mum.
Dr Rogers suggested Patterson's children never knew her mum to forage for wild mushrooms.
'I suggest this is a story you have made up for this jury, agree or disagree?' Dr Rogers said.
'Disagree,' Patterson replied.
Patterson accused of hiding death caps in food
Dr Rogers suggested Patterson didn't chop up the death caps but blitzed the lethal mushrooms into a powder.
'I disagree,' Patterson said.
Dr Rogers suggested she powdered the death caps to hide them in food.
'I disagree,' Patterson said.
Dr Rogers reminded Patterson she had previously ground non-lethal mushrooms into a powder and hid them in muffins which she fed to her daughter.
'I did do that once yes,' Patterson said.
Patterson bought dehydrator same day she allegedly picked death caps
Patterson was reminded that telecommunications expert Dr Matthew Sorell gave evidence her phone pinged near a basestation which meant a possible visit to Loch on April 28.
Dr Rogers suggested Patterson was in Loch on that date.
'I don't know [if I was in Loch that day],' she said.
Dr Rogers suggested Patterson went to a death cap sighting zone previously posted on iNaturalist.
'Incorrect,' Patterson said.
Dr Rogers suggested Patterson read the iNaturalist post put up on April 18.
'Disagree,' Patterson said.
Dr Rogers suggested Patterson drove specifically to Loch to find death caps on April 28.
'Disagree,' Patterson said.
'And I suggest you found some, then within two hours went and bought the dehydrator,' Dr Rogers said.
'I did buy that that day yes,' Patterson said, but denied she bought it to dry death caps.
Patterson asked why she would serve her kids the leftovers
Patterson has been quizzed on why she served her kids leftovers from a lunch despite being aware some guests were sick.
'It was the same lunch yes,' Patterson said.
'Even though you thought you had food poisoning from the same lunch?' Dr Rogers asked.
'I didn't think that,' Patterson said.
Dr Rogers has suggested Patterson told various health officials, medical staff and police she served her kids the same meal eaten by her lunch guests.
Patterson said it was minus the mushrooms and pastry so 'it wasn't the same' meal.
Dr Rogers also asked if Patterson knew some lunch guests were sick then why would she serve leftovers to her kids.
Dr Rogers suggested Patterson lied about serving her children the leftovers minus mushrooms and pastry.
The jury previously heard evidence Patterson told child services officer Katrina Cripps she cooked two Wellingtons which she put aside for her kids.
Patterson disagreed.
