"If she dies I'm gonna burn this whole place down I swear," the man from Baxter spat through tears sitting in a Dandenong dock.

He is accused of stealing the Holden Commodore involved in the deadly smash on the South Gippsland Highway which has left his 17-year-old girlfriend Dhakoda Nicholson fighting for life.

"My last memory is her screaming my name with blood all over her," he told the magistrate.

"I didn't try and run, I didn't rummage through my bag, I went to the back seat to try and get her out I was worried about her.

"She might not be here tomorrow, bro."

Witnesses allege the teen attempted to flee the scene and find a knife in his bag to avoid arrest.

His friend and driver of the car, 20 year-old-driver Frankston man Dylan Cassidy, remains under police guard in hospital after he was tackled to the ground while he attempted to flee the scene.

Byron Hampton, 16, and Jordy Kirkwood, 18, were killed when the car careered into an oncoming vehicle.

The court also heard today that Ledlin is accused of bashing a man with a baseball bat and taking part in a violent aggravated burglary at a Frankston home in March which netted half a million dollars' worth of stolen property.

Police allege the teen carried knuckle dusters and a baseball bat to the home on Oliver's Hill before members of the group stole jewellery, watches and a television.

His lawyer requested he be bailed as soon as possible.

"He is suffering from after effects of this horrible incident and is not surprisingly completely devastated by the death of friends and condition of girlfriend," he said.

"This is the type of lesson no one would ever want to be subjected to. He is desperate to get out."

The magistrate wasn't confident Ledlin was suitable for bail and will reconsider the case tomorrow.

The occupants of the other vehicle – a 39-year-old woman and two girls aged six and nine, all from Lynbrook – were treated for non-life threatening injuries.

Family and friends pay tribute to teens

Hampton's family paid tribute to him, saying he "always put others before himself".

His mother, Nicole Hampton, laid flowers at the scene of the crash yesterday, telling reporters her son was a "hard worker" who was attending school at Hallam Senior College while also working towards his apprenticeship.

He is survived by two sisters, aged four and 10 and two brothers aged 13 and 18.

Devastated friends and family have taken to social media to express their grief and shock at the deaths.

"RIP my baby cousin," Aimee Thompie wrote on Facebook to pay tribute to Hampton.

"You had only just turned 16."

A friend of the teen boy killed said he had "a good heart".
