Episode Title:
The Witches' Tea Party.
Episode Description:
After respawning, Subaru finds himself at wit's end and decides to consult Echidna. However, he is instead put through the second trial, in which he faces scenarios where others react to his many deaths and causing him to break down. Fortunately, Rem inexplicably appears before him and calms him down. However, Subaru realizes something is wrong and it's revealed that the person before him is actually the Witch of Lust, Carmilla. Echidna, who sent her to calm Subaru, then confronts him and, after learning about his plight, offers to make a contract with him, allowing him to console her at any time. However, just as he is about to accept, the other witches interrupt and warn him not to trust Echidna. In response, Echidna comes clean to Subaru, revealing her desire for his Return By Death and that she was the one who put Beatrice in the library to await "that person", who doesn't exist. Realizing that Echidna is a sociopath, Subaru cuts ties with her but is then met by the sudden arrival of Satella.
