The brother of the accused Bourke Street killer has been jailed for a catalogue of offences including throwing an object at his mother in a drug-affected rage when she failed to make him a toasted sandwich quickly enough, a court has been told.
Angelo Gargasoulas, 26, pleaded guilty to 13 charges at the Melbourne Magistrates Court on Thursday, including recklessly injuring his mother and intentionally injuring his partner. He faces two months in jail.
He was allegedly stabbed by his brother, Dimitrious "Jimmy" Gargasoulas, in the early hours of January 20, the same day as the Bourke Street tragedy.
Mr Turner said that Angelo Gargasoulas is still suffering mentally and physically from the "events earlier this year", and was still being treated in hospital for his injuries.
Dimitrious Gargasoulas allegedly killed six people and injured 31 more in the Bourke Street rampage. He has been charged with five counts of murder.
The court heard that Angelo Gargasoulas was hungover and coming down from the effects of drugs when he attacked his mother on July 8 last year.

His mother, who was intoxicated at the time, was making him a toasted sandwich in their Windsor apartment. Gargasoulas demanded that she hurry up.
He reacted to his mother's response, throwing an object police say was possibly a vacuum flask at her face.
She suffered a bruised eye, a cut to her lip and other injuries, and fled the apartment.
About two weeks later, on July 23, 2016, Mr Gargasoulas also attacked his partner over a trip to Crown Casino. Mr Gargasoulas did not want him to go, and threw a box-cutter at him.
His partner, who was cut in the attack, ran into the apartment where the two men continued to argue.
Police arrived to find the box cutter in a pot plant and a kitchen knife on a bedside table.
Gargasoulas also admitted to stealing a backpack from a cab containing more than $3000 in the driver's wages; leaving a police station without providing a breath test after being pulled over; refusing to comply with a roadside drug test; driving without a licence; driving down Russell Street while disqualified and stealing a car while on bail
Magistrate Franz Holzer said Gargasoulas' crimes were serious, particularly as he had a history of family violence.
Mr Holzer said he understood that things were difficult for Gargasoulas and his family in the "current climate" but said he had to sentence him based on the nature of his charges and his criminal history.
Gargasoulas, who previously breached a community corrections order, will also be subject to another 18-month order after he is released from prison in April.
This included 100 hours unpaid community work, a series of treatment programs for drugs, alcohol, mental health and to reduce his risk of reoffending.
He will lose his licence for four years and three months for refusing drug tests and stealing a car.
Mr Turner said Gargasoulas was in the "grips of a severe ice addiction" at the time of his crimes and had a "toxic" relationship with his partner, who was also a heavy ice user.
His relationship with his mother had also deteriorated during this time. His mother drank alcohol heavily, and became "abusive" when she did, "causing him offence", while he was using ice daily.
Mr Turner said that his client began using ice when he met his partner, when drug use became "part and parcel" of their relationship.
His work ethic declined as his drug use grew over the years.
While he was addicted to the drug ice during his crimes, he no longer used it, Mr Turner said.
More details about the brothers' backgrounds also emerged in court during the hearing.
Mr Turner said that Angelo and Jimmy grew up in South Australia with their father and stepmother, in what Gargasoulas described as strict and "typical Greek Catholic family".
The brothers only saw their mother about four times a year on school holidays.
Angelo Gargasoulas moved to Melbourne in 2006, where he attended high school until halfway through year 12. He worked at men's fashion stores and in bars, the court was told.
