She also suppressed details of those arguments that related to the ongoing police investigation and other matters relating to the case.
Mr Linder's brother was in court, supported by a detective. He was joined by a friend of Mr Linder, and the pair shared a moment together before breaking down in tears.
Friends of the accused were also in court. One of the youths made an appearance in the dock on an unrelated assault charge about an hour before the accused.
As the group arrived at court their mood was jovial. They joked about the accused and bragged to one another about where they had slept the night before - some in Albert Park and others in a sport clubhouse.
But soon, the gravity of the situation appeared to set in and the group became upset. Several teenage girls cried as the accused appeared, and one yelled out, "Love you", despite being told to "stay calm" by court staff.
The group also seemed to know Mr Linder, discussing him by name and recognising that his family were in court.
Lawyer Siobhan Buckley, acting for the accused teenager, did not apply for bail and argued that naming him and publishing his photograph would impinge on his right to a fair trial. "With respect, it is early days," she said. "It's not as if everything is known for certain."
Judge Kiernan remanded the 17-year-old in custody until this afternoon's hearing.
Yesterday, the police investigation continued. A post-mortem examination took place and officers were back in Mills Lane speaking to people who frequent the area.
