This episode is all about fidelity. The big day has arrived for our eight remaining Tools as they are made to write some heartfelt wedding vows before escorting their other halves up the aisle in a mock wedding ceremony. Will nerves get the better of them? What happens when they find out the wedding is not for real? It ends far from happily ever after for randy Tool Liam when footage of the boys behaving badly on a night out is revealed to girlfriend Toni. Once fidelity lessons are complete, host Rick Edwards reveals who's still on course to graduate and win the £25,000 prize - and who's going home a Tool.
