Thea manages to find the box Hearth's key unlocks, but only finds an incomplete note inside it. Curious how Klaus knew to recruit her into Lamplight, Thea tries to reconstruct the note by writing numerous variations, including one that says "Klaus loves you." However, she accidentally drops the note in Lily's room. Lily discovers the note and gets flustered, and through a series of misunderstandings the note is spread around the mansion, leading Erna, Monika, Sibylla, and Sara to believe the note is directed at them instead. Klaus then announces he will need one partner to accompany him on his next mission, causing the girls to compete for the position. Meanwhile, Grete assists Thea with deciphering Hearth's note, and with some information provided by Olivia, Grete deduces it really says "Klaus saved you." At the time Thea was rescued by Hearth as a child, Hearth had already arranged for Klaus to train her as a spy to help her deal with her trauma. Upon returning, Thea clears up the misunderstanding about the note with the others, but she admits the whole situation lightened her mood. Klaus quietly observes and concludes that making Lily the team leader was the right choice, due to her ability to make others smile. Afterwards, Klaus congratulates Lamplight for officially graduating, and informs them they will focus on defeating Serpent, who appear to have gone rogue to pursue their own goals apart from Galgad's.
