Re:ZERO season 3 episode 14: A brief recap

Re:ZERO season 3 episode 14, titled Theresia van Astrea, shifts its focus to the emotional battle between Wilhelm and the reanimated Theresia. The episode delves deep into her story, opening with a brief flashback of their first encounter before transitioning to their present confrontation.
Despite Wilhelm's best efforts, Theresia easily overpowers him. The battle takes a turn when Heinkel arrives, drawing Theresia's attention away from Wilhelm. Unable to redirect her focus, Wilhelm watches helplessly as Heinkel—outmatched by the former Sword Saint—faces imminent defeat. However, just as Theresia is about to strike the final blow, Reinhard enters, stopping her attack.
As Reinhard unsheathes his sword, Wilhelm pleads with him not to kill her, but Reinhard remains resolute, reminding Wilhelm that the real Theresia is already gone and that this reanimated version cannot be allowed to roam free. Theresia's attack nears Reinhard, but he strikes her down, restoring the light in her eyes as her memories return.
A series of flashbacks unveils her past—how she received the Sword Saint's blessing, the burden it placed on her, and how her initial inability to bear that responsibility led to deaths of her close ones. The story further explores her budding romance with Wilhelm, who took on the duty of wielding the sword in her place.

Their happiness was cut short when Theresia chose to fight against the White Whale, which led to her losing the Sword Saint's blessing as it got passed to Reinhard. Ultimately, she crossed paths with the Witch of Vainglory, Pandora and lost her life.
Back in the present, Theresia shares a heartfelt farewell with Wilhelm before passing away in his arms. Afterward, Heinkel blames Reinhard for Theresia's death, but Wilhelm intervenes, asking Reinhard if he regrets his actions. Reinhard stands firm in his decision.
The episode ends on a somber note as Wilhelm acknowledges his mistakes and accepts that Reinhard did what had to be done, and asks him to assist in other battlefronts, while Heinkel remains unable to accept this outcome.
What to expect in Re:ZERO season 3 episode 15? (speculative)
Re:ZERO season 3 episode 15 is titled Ugly Dinner Party. After the conclusion of the fight between Wilhelm and Thearesia, the anime sequel will now focus on the remaining showdowns including Al vs. Capella and the others. As stated in the preview synopsis, the names of the twin Sin Archbishops will be revealed in this installment.
Moreover, Julius and Ricardo will also get overpowered by their opponent who is devouring anything the protagonist's side throws at him. However, one interesting thing in this chapter might be Ricardo's real name which was kept a secret since season 1.
