S01E28: The Long-Awaited Reunion

On the way to the Sanctuary, Subaru unwittingly finds himself invited to a witch’s tea party, where the hostess introduces herself as Echidna, the Witch of Greed. Subaru is alarmed, but Echidna encourages him to sit and drink his tea before it gets cold. When he somehow makes it back outside after a conversation with Echidna, he finds Otto lying on the ground, battered and beaten. Then, before he even has a moment to assess the situation, Subaru himself is attacked.
