The Mustangs have made it to the final eight, but Marnie's in a slump - Anusha's tactics divided the team, Lara's lecturing her on leadership, Liv is giving her the stink-eye, and even Gabe is sick of being used as a shoulder to cry on when he wants to be so much more. Could life suck any harder? Marnie has to girl up to a hostile team and rally the troops - it's the semis this weekend, so it's time to set differences aside and do some hardcore training - Mustangs style.
