The following article contains spoilers for To Your Eternity: Season 2 Episode 6, “Heretics Betrayed,” now streaming on Crunchyroll.

Picking up where last week left off, To Your Eternity: Season 2’s sixth episode opens with Kahaku proposing to Fushi, asking the immortal to take his hand in marriage. Unsurprisingly, Fushi turns the Leader of the Guardians down. While they struggle to articulate the specifics, it’s clear that Fushi can sense attraction as a tangible force, and it’s one they don’t feel in return for Kahaku.

Unfortunately, Kahaku continues to insist otherwise and embraces Fushi, causing the immortal to run away and throw up. Fushi is initially surprised at the extremity of their own reaction but quickly realizes why — they’re currently in Parona’s body.

After Kahaku attempts to pursue Fushi further, Fushi firmly rejects him and explains why they had such a volatile reaction. To Kahaku’s shock, Fushi goes into explicit detail about the tragic, gory end Parona met at the hands of Kahaku’s ancestor Hayase, with images of that death rising to the surface when Kahaku hugged the immortal.

Kahaku’s constant lust for Fushi has been an unremarked-upon background element for the past several episodes, and the fact that the Guardian’s leader seemed especially enamored with Fushi’s Parona form was always an uncomfortable element for the reasons this episode lays out. To see that fact addressed so frankly in the show itself is a pleasant surprise, hopefully marking an end to Kahaku’s advances on the immortal.

Kahaku isn’t the only one of Fushi’s allies to see their flaws directly addressed in the episode. Bon continues to struggle with whether he wants to be a genuine ally to Fushi or simply exploit the immortal to his own ends, and that struggle reaches a boiling point.

Prince Bon Is Torn Between His Loyalty to Fushi and His Kingdom

Confronted by the Church of Bennett’s Grand Cardinal Cyrila, Bon is urged to surrender Fushi, who the Church regards as a heretic. Bon initially refuses, but when Cyrila promises that he can help him become king, the prince takes pause. Bon, while mostly benevolent up to this point, has still been using Fushi as a means to become king, and this would merely serve as a natural extension of that.

Twisting the knife further, Cyrila threatens Bon’s Kingdom of Uralis — should Fushi be seen as affiliating with them, the Kingdom would be seen as abetting an iconoclast. With his family and subjects now in the crosshairs, Bon sadly relents.

Fushi winds up captured and forced to attempt to resurrect the church’s elder Hanoi in a public display to test their powers; should they succeed, they would not be seen as a heretic after all. Bon briefly panics, having kept Fushi’s ability to revive the dead a secret from the immortal, but is surprised when Fushi is unable to resurrect Hanoi. As a result, Fushi is taken away from the Church, who also renege on their agreement with Bon, capturing him and his squire Todo.

Fushi Is Left at the Mercy of the Church in To Your Eternity’s Most Bloodcurdling Scene

Sealed in an iron cage, Fushi tries in vain to escape. When the Beholder asks what drives his creation to get out, the immortal declares a desire to save their friends from certain doom. After all, they reason, everybody is deserving of a dignified death on their own terms, and the Beholder is left seemingly impressed by Fushi’s newfound understanding of that aspect of humanity.

This vow to save their friends looks like it’ll serve as a heroic second wind to motivate Fushi to escape, which makes it all the more tragic when the rest of the scene plays out. The Church of Bennett pours molten iron into the cage, repeatedly burning Fushi as their regenerative power struggles to keep up and the cage is filled to the brim.

It’s one of the series’ most harrowing sequences, thanks in no small part to the episode showing only brief glimpses of the immortal’s struggle, with most of the gory details left to the viewer’s imagination as Fushi screams in agony. While it’s surprising that it’s taken so long for the show to mine horror out of its protagonist being immortal, being buried alive by a scalding substance is that premise taken to 11, and it makes for one of To Your Eternity’s most memorable — and upsetting — scenes to date.

With Bon and Todo left in cages dangling precariously over a river and Kahaku and the Guardians seemingly unable to rescue Fushi from their ironclad prison, all seems lost for the heroes of To Your Eternity. Of course, if anyone can escape from impossible situations, it’s Fushi, and the last shot of the episode shows their eyes opening deep within the solid metal cage, indicating that the immortal may be down but is far from out.
