Only recently on Emmerdale, Lachlan White killed his mother Chrissie White and grandfather Lawrence White in a deadly car crash.
The unhinged teenager confronted his mother, who had forced his girlfriend Belle Dingle to break up with him, as he took hold of the steering wheel and drove the car in front of an oncoming lorry.
However, with Lachlan's aunty Rebecca White, who knows exactly what he did, unconscious – it looks as though he will do anything to keep his deadly secret from getting out.
In a new chilling trailer released by the award-winning ITV soap, it shows Lachlan squeezing breathing tubes, which are presumably Rebecca's as she's currently on a life support machine.
As the unhinged teenager appears to clutch the device, keeping her alive, he mutters: "I'm sorry..."
Is Rebecca going to be Lachlan's next victim or will he get caught just in time?
However, what the character doesn't realise is that his best friend Gerry has a voicemail recording of the entire incident.
Lachlan rung him just as things escalated in the cat, with the entire collision recorded as evidence on his mobile phone.
However, Gerry hasn't been able to find his phone, or listen to the voicemail just yet, after his device going missing.
But on Friday's episode, Belle found it underneath Lachlan's bed in the hospital – putting it in her pocket.
Soap watchers now think the teenager's former girlfriend will be the one to 'expose' him and she will listen to the incriminating voicemail.
Emmerdale continues on weeknights at 7pm on ITV.
