Well, In Other Words - S2.E5

After Illya inadvertently blows up her house's bathroom wall, her family comes over to Luvia's house to use her bathroom, where Kuro causes more trouble for Illya. Later, as Rin and Luvia ask Illya about how she used the Archer Card in the manner she did, Illya's statement of wanting to return to a normal life angers Kuro, who reveals she herself possesses the Archer Card and escapes. The next day, Miyu is summoned by Kuro, who claims Illya's wish of a normal life excludes Miyu and the other people she had met as well too. However, Miyu has faith in her friendship with Illya and uses the Saber Card to stand up against Kuro.
