"They encourage him and eagerly await his return. It's a warm welcome he hasn't received at school in a long time."
The family said that they do not know how much longer his hospitalisation will have to continue, adding: "Our little knight, as courageous as ever, continues to fight and train, and we will remain by his side to support him no matter what."
London nurse Vicky Diplacto, whose brother was paralysed after an accident overseas, set up the GoFundMe appeal to help.
Autistic Bravery, now 24, was in supported accommodation at the time of the attack but allowed out unsupervised.
He intended to select and kill someone, a court was later told.
Bravery, who was 17 at the time, pleaded guilty to attempted murder and was handed a life sentence with a minimum term of 15 years.
He was back in court earlier this year, as he was jailed for 16 weeks after he was found guilty of assaulting two nurses at Broadmoor, a high-security psychiatric hospital in Berkshire, in September 2024.
In 2020, he was given a 14-week jail sentence after admitting to attacking staff at the same hospital.
