Everyone has been nice to Crona since she came to Shibusen, and this is especially apparent during a party one night. Kid is supportive of Crona proceeding at her own pace, and Black*Star promises to beat up anyone who bullies her. Since Crona isn’t sure why everyone is being so kind, Maka explains that it’s natural since they’re all friends. These warm feelings stay with Crona until she leaves the party to go home, and that’s when Medusa appears. Despite Medusa’s small body and seemingly gentle nature, Crona is deathly afraid of the witch. Medusa claims that she came to see Crona and was very worried, but what she wants Crona to do now is to spy for her in Shibusen and to find a secret vault. Crona doesn’t want to betray her new friends and new home, but Medusa uses her status as Crona’s mother to coerce Crona to do it. Crona is very conflicted about this, but she still ends up going underground Shibusen to an off-limits area to try to find the secret vault. Before Crona can get very far, she’s caught by Marie, and Ragnarok makes up the excuse that they got lost. Marie believes them since she’s also lost, and it takes two hours for her to help Crona find her way back to her room. Nevertheless, Marie tells Crona to come to her if she’s ever bothered by anything again. Once back in her room, Crona is paid a visit by Eruka in her frog form who’s able to communicate with Medusa via the snakes in her body. Since Crona doesn’t think that she can find the vault, Medusa decides instead to take advantage of Marie’s kindness towards Crona and gives Crona a pen with a listening device inside to plant in Stein’s laboratory. Crona thus goes to Marie under the pretense that she wants to talk, and Marie brings her to Stein’s laboratory. While Ragnarok has Marie distracted, Crona puts the snake listening device inside Marie’s coffee, and she then watches as Marie drinks it. Afterward, when Crona goes to leave, Marie stops her because she almost left the pen behind. Eruka explains later that the snake will allow Medusa both to eavesdrop and to accelerate the madness in Stein. After hearing over the radio how fondly Marie talks about her to Stein, Crona quietly returns to her room and retreats to a dark corner with a pillow. As the darkness around her spreads, Crona starts crying.
