Spoilers on its identity, story and destiny
Attention, you will find below some important elements about the story of the game.
It's suggested after a few chapters that Jeritza is actually the Knight of Death, after rescuing Flayn, he only appears in this form in the game. Later on, if you have Mercedes and Caspar in your team, and you don't take the road to Edelgard, you will be entitled to a special appendix that will offer some answers. Jeritza is actually Mercedes' young half-brother, raised by Bartels. The events that led to his transformation into a Knight of Death are never detailed, but it is suggested that they were unpleasant. He has become ruthless and is visibly fascinated by death, the death of others and his own. His fate changes a little depending on the road he takes, but not significantly.
Black eagles and Edelgard's road: He assists you during the assault on the monastery during chapter 12. Since the patch, he automatically joins your team in the 2nd part of the game. Afterwards, you learn from Manuela that he has apologized to her for his past actions. He also has an appendix with Anna if you have his DLC. He is entitled to several different purposes depending on his materials.
Black Eagles and Rhea Road, or Golden Stags: The annex mentioned above can be made. At the end of the latter, he offers a relic of Lamine to Mercedes. The next meeting is at Fort Merceus, it draws your army forces out of the fort to save them from the bombardment of the Dark Snakes. He is met one last time during the assault on the capital, he is then simply killed.
Blue Lions: The appendix can be done, but the rest changes a little. A fight to the death takes place in Fort Merceus, once defeated, you get a small cutscene involving Mercedes, who is crying next to her brother's corpse.
