Zeke was dying, stupidly, but death was still death regardless of your opinion on the cause.

The process is a bit long, it has to go back almost 4 years.

It cannot be denied that your marriage also caused Zeke to imperceptibly join the Survey Corps, yet Levi still held a deep grudge against Zeke because Zeke was responsible for Erwin's death. He would constantly talk about killing him in front of him, and Zeke, your charismatic man, would only sarcastically mock it.

Now during this plan, Zeke and Levi as well as Levi's men settled in a forest to prepare for the next mission, but Zeke had an escape plan and this plan was carried out by turning Levi's men into pure Titans and distracting Levi. But Levi without any expectations killed all the Titans that were once his men, captured Zeke again and this time didn't spare even the slightest toture.

Zeke was then lying on a wooden cart, bound and half-naked, a long metal rod was stuck in his stomach, and even the slightest movement would cause the metal to explode, and Zeke did so without any concern.

Given his Titanic ability after the massive explosion, his body was revived using a pure Titan, but Levi's injured body was quickly whisked away by Hange for reviving.

Now Zeke stood with his hand resting on the large ribcage of pure titan, safe and sound, but naked and a little dazed, his piercing gray eyes staring straight at you, his precious wife, careless to Floch and Jaegerist Army that standing before him.
