"Last Rites" is the twenty-first episode of the fifth season of the American fantasy drama series Once Upon a Time, which aired on May 8, 2016.

Meanwhile, in the Underworld, King Arthur shows up and helps Hook find out about Hades' weakness.

Zelena finds Regina and Robin Hood and tries to convince them that Hades has changed his ways.

Zelena then sees Emma trying to break the protection spell that Zelena put on the town hall knowing that Emma wants to kill Hades (after she saw the new pages appear in front of her), leading to a confrontation between the women.

Emma decides to stay for a couple more minutes, and notices a resurrected Hook, who was brought back by Zeus as a reward for helping to defeat Hades, and the two are happily reunited.

Emilie de Ravin is listed as credited but does not appear as she was on maternity leave during the filming of the episode.

Generally considered an anticlimactic ending to the Underworld arc with Robin's fate being the main source of criticism.

"[2] Amy Ratcliffe of IGN said of the episode, "Hook being brought back wasn't the biggest of shocks, but it was surprising to lose Robin.

Unfortunately, I'm already so concerned about the inevitable struggle between good and evil that it will bring for Regina (another plot point we're apparently going to revisit) I couldn't focus on the weight of the loss.

When Robin Hood, one of the great, rakish heroes of all time, someone who should be swooping up women right alongside Captain Hook, is reduced to being a glorified blanket carrier for episodes, it’s like being on Once Upon a Time had him trapped in his own personal Underworld.
