It’s all come down to this moment, Gladiators. The Scandal series finale airs this Thursday at 7 p.m. ET, and if the sneak peek is anything to go by, it’s going to be an episode that will leave fans talking for weeks.

The episode “Over a Cliff,” written by Shonda Rhimes and directed by Tom Verica, is already being billed as “powerful,” and with good reason. “The episode marks the culmination of Olivia, Mellie, Fitz and the Gladiators’ journey as we know it,” says the network in a statement. “With the existence of B613 exposed to the world, the Gladiators make the ultimate sacrifice in order to take down Cyrus and Jake – but how far will they go to get justice?”

After the finale, Jimmy Kimmel Live! will celebrate the end of an era with a jam-packed Scandal after-show, featuring Rhimes, Kerry Washington, Darby Stanchfield, Katie Lowes, Guillermo Diaz, Tony Goldwyn, Jeff Perry, Bellamy Young, Joshua Malina, Scott Foley, Joe Morton, Cornelius Smith Jr. and George Newbern. To top it all off, Chaka Khan will give a special performance.
