A small leak will sink a great ship. I

'''A small leak will sink a great ship. I' (TBA, TBA) is the 11th episode of the second season of The Ancient Magus Bride'' anime.

Synopsis
It's learned that Lucy suffered from the same curse-like condition as Simeon, and most of the faculty set out to figure out how to break the curse. Meanwhile, Zoe inadvertently bonds with Lucy, who is adamant about making more money to pay for her tuition at the College. However, Chise, Zoe, Rian, and Isaac intervene and volunteer themselves to handle Lucy's job at the Waste Tower, to make some money for her.

Summary
Philomela awakens on her bed in her dorm room and notes that a scent is fading. At the infirmary, Marielle informs Chise and Elias that the unconscious Lucy was also afflicted by the same curse as Simeon. Unaware of the curse's source, the Book of Carnmagos, Marielle gives Chise an explanation about it and that it's draining her power. Elias suggests that he could trace the magic's source, but when he tries, it fails.

Hence, Elias notes that they'll have to catch the culprit in the act to figure out who's behind the curse. It's also surmised that Chise was inadvertently feeding Lucy spare energy that allowed her to stay awake for so long. This feat could be accomplished due to Chise being a Sleigh Beggy. Speculations of motive and reasons are discussed between Elias, Marielle, and Alexandra. Elias decides to solve the mystery behind the curse attacks for Chise and to become Simeon's "friend". Chise insists on helping Elias; however, he declines, and Alexandra backs him up.

Walking down the hallway, Chise runs into Philomela, who asks for more potpourri relaxant. Chise happily agrees to make her more and asks Philomela if she'd like to make some more with her, to which she agrees. Unbeknownst to the two, an elusive figure was eavesdropping on their conversation.

Afterward, Lucy attends a small class about runes and learns about their history and uses. One such rune catches Chise's eye because it resembles "thorns", and the teacher says its name is Thurisaz. The teacher further explains that the Thurisaz rune is related to Giants, Faries, Thor, and thorns and bramble. With that explained, the teacher informs his students that they'll make an amulet out of it. Zoe, also in the class, asked Chise about Lucy's condition.

That night, Zoe visits Lucy in the infirmary, who awakens from her unconscious state. Although Zoe had intended to visit briefly, Lucy asks Zoe if she could pet his snakes. After she does, Lucy briefly talks about her family's spiders. Zoe attentively listens, but tries to mention the special meaning behind a Gorgon's snakes. However, Lucy fell asleep before Zoe could explain, and Seth, who slept in the nearby bed, was shown to have eavesdropped on their conversation.

At Elias' House, Chise, alongside Ruth, explains to Silver that Elias and she will be staying at the College for the time being. She keeps the full details vague due to the circumstances and then, with the help of Hazel, delivers three whole sheep to the The Hounds, who accept it.

Later, Chise walks home with Hazel, and the two have a heart-to-heart about the payment Chise had to give to the Hounds for the Male and Female Werewolf couple. They also discuss Chise's impulsive need to help others and its costs to her.

That morning, Tory hands out bags of candy with Narcisse to the students at the College for Hallowe'en. It's revealed that they're doing it because of how short-handed the staff is due to the recent incidents happening in the College. Meanwhile, in the hallway, Alice bumps into a couple of students, and she asks one of them to lend her their costumes when they're finished with it.

Elsewhere, Chise helps Zoe stop Lucy, who has awakened, to get back into bed to rest. On the other hand, Lucy is adamant about working to pay her tuition. She also claims that her brother hasn't paid for any of it, believing it's a way for him to boss her around. Just then, Rian and Isaac and it's learned that Lucy wants to go to the Waste Tower to make some money there. Lucy insists on going despite her friend's refusal, so Zoe, Chise, Rian, and Isaac go in her place.

At the Waste Tower, Philomela was with Fabio trying to gain access into the tower, but couldn't and was soon joined by Chise's group. Zoe explains the circumstances to Fabio, who accepts the group's help and introduces himself to them all.

Back at the infirmary, Ruth stays behind to act as Lucy's guard. They're soon joined by Sigrid, who assures Lucy that she'll find another job to perform, but is perplexed to learn that Lucy had friends perform her job in her place.

Returning to Chise's side, Philomela warns Chise about Fabio, who opens the door to the Waste Tower and warns them about its danger inside the tower.

Meanwhile, Principal Liza talks with Florence about all of the problems piling up within the college. However, she relishes them as once they're solved; her reputation will increase. Liza then reads a letter addressed to her, which reads that Philomela will be withdrawing from the college.
