Tonight on Emmerdale Lachlan (manoeuvred by Thomas Atkinson) finally succumbed to his conscience as he reasoned with Rebecca Pale (Emily Head).
After Rebecca attempted to be a thorn in his side, Lachlan abandoned her on to the ground, propelling himself into an emotional rage.
But after realising that he had hurt his sister, he decided to explain the entire situation to her.
This guilt-ridden confession saw him party what really happened in the car chase that killed their nurturer and grandfather.
But Lachlan’s out-of-character confession may lead to his ultimate downfall, as Rebecca is now the however living person who knows about his string of murders.
If Rebecca someway finds a way out of the horror-movie style cabin in the woods, Lachlan will absolutely be done for.
But until then, he is left side visiting his sister each day to confess his sins.
However Rebecca didn’t long for to hear the details this evening, as she pleaded for him to stop telling her what he had done.
He interpreted: “I feel like I have to tell somebody because – do you know what it’s opposite number living with this?
“I caused the crash, I killed mum and granddad.”
Lachlan studied on to describe in excruciating detail what had happened, as he added: “I turned the swing straight into the path of that truck. It wasn’t an accident.
“I ethical snapped. I didn’t mean for it to happen.

“I just grabbed the wheel and didn’t think about the consequences.”
As if that wasn’t bad adequate for poor Rebecca, she then had to hear about how Lachlan killed his most suitable friend Gerry Roberts (Shaun Thomas).
Coldly, he said: “Gerry wasn’t an accessary either.
“I killed him too. I killed all of them, Rebecca.”
In the final moments of his psychotic orate, Lachlan admitted: “Thanks for listening, It feels good to get that off my trunk – it really does.”

But as he got up to leave, Rebecca pleaded for her life, yelping: “I won’t blow a word – no one would believe me anyway. It would be my word against yours!
“Of about Seb, please Lachlan, he needs his mother!”
As he stepped out of the door, he looked again at his trapped sister and smirked: “Does he? ‘Cause I’m much better without colliery.”
If Rebecca escapes, she may bring down the killer teen, but will he stab to silence her once and for all before that?
