Lachlan (played by Thomas Atkinson) made the deeply disturbed decision to swerve the wheel from his mother Chrissie White’s (Louise Marwood) hands during their high-octane car chase through Emmerdale last month, and it resulted in death and destruction.
Yet while both Chrissie and Lawrence White (John Bowe) died almost instantly in the mangled car wreck, Lachlan survived with barely a scratch and Rebecca (Emily Head) was left in a coma for weeks.
Fans have been eagerly waiting for the mentally ill youngster to finally get the justice he deserves on the ITV soap ever since, and it could finally be happening.
Lachlan’s grip on reality has become ever more tenuous as his feelings about the horrific incident continue to flip-flop, but as Rebecca gradually gets better he’ll have a huge decision to make.
Next week though, Lachlan can’t help getting overcome with guilt at every turn as he witnesses his only remaining family member struggling with her injuries.
On top of that, Rebecca is still unable to make sense of her jumbled memories the day of the accident – a ticking clock for Lachlan.
But rather than wanting to shut her down, the psychopath will have a change of heart and feel obligated to protect his relative.
Watching Rebecca struggle to complete even the most basic of tasks, Lachlan, whose nickname “Lucky” was affectionately bestowed by his family, reveals a totally different side of himself.
Yet as the pair become closer, it could be the chance for Lachlan to confess the truth about what happened that fateful day.
Meanwhile, another character struggling with their own trauma in the Dales is Ross Barton (Michael Parr).
Having suffered from a horrific acid attack at the hands of drug dealer Simon McManus (Liam Ainsworth) last week, Ross could face permanent scarring on his face from the destructive substance.
He’s still unaware of exactly who was behind the attack, and it could destroy his relationship with Debbie Dingle (Charley Webb) forever if he truly discovers the truth.
In the meantime though, Ross struggles to cope with his new existence, still harbouring deep upset from the trauma and fighting through the pain.
Barely able to control his emotions, Ross confesses that he wishes their mother Emma Barton (Gillian Kearney) had accidentally shot him dead instead of their beloved younger brother Finn.
Understandably panicked about his little brother’s state of mind, Pete does his best to be the emotional support and rock Ross needs.
Pete tells him he loves him and gives him some tender words of encouragement, but the worry won’t go away, and Ross ends up breaking out of hospital.
