After years of failing to compete his task, Sideshow Bob will finally kill Bart Simpson.

The murder will part of this year’s The Simpsons’ Treehouse of Horror episode.

Speaking at this weekend’s ATX Festival in Austin, Texas, executive producer Al Jean said it’s time for Bob to finally get his man “I hated frustration comedy so we’ll scratch that itch,” Jean told EW.

So Bob will finally somehow actually execute Bart—and then won’t know what to do with himself after his life’s mission has been accomplished.

But don’t worry, Bart will be back in the show after the Halloween episode.

Producers also revealed Spider-Pig will make an appearance during the show’s 27th season.
