Seriously the whole thing was hilarious. The best bits started from 2:55.
Louis' terrified face:
Louis: I'm going to go with Carolynne, I wanna keep Carolynne!
*Carolynne begins crying with happiness*
Dermot: So you're gonna send home Rylan?
Louis: I wanna save Rylan I wanna save Carolynne *scared face*
Dermot: WHO ARE YOU SENDING HOME LOUIS?! LOUIS THE NAME OF THE ACT YOU'RE SENDING HOME. WHAT DID YOU JUST SAY?
And then the best bit...
Louis: I WANNA TAKE IT TO DEADLOCK! *audience screams as the drama hits the roof, Louis does scared face and Dermot rolls his eyes*
