During his last episode back in January 2018, Pat attacked Luke with a stone but after a struggle, he managed to get away.
A car chase then ensued, with the pair speeding down a road before Pat managed to force Luke off the road.
Reaching for his gun, Pat calmly walked over to the car and shot Luke as he sat in the driver’s seat of his vehicle.
Turning back to the car, he shot the petrol tank which engulfed the car in an enormous fireball.
Love Island begins tonight at 9pm on ITV.
