Moriarty drives a jeep with Sherlock Holmes, Fran, and Nora across the plains. They see a huge black cloud ahead, but Holmes looks at it through binoculars and sees it is a massive swarm of Geist Grimm. He then sees Victor and the Other Fran up ahead. Nora says she didn't know Fran had a sister, which confuses Fran. Holmes says it looks like the Other Fran is artificial. Fran suddenly loses her temper and releases a lot of electricity before jumping out of the jeep and charging at the pair. The others are forced to jump out before the jeep explodes. Nora comments she thought Holmes was smart enough not to say something like that in Fran's presence, which makes Moriarty smile and pat her head.
Holmes says they should take care of the Geist before they reach Chaldea. Nora offers to handle the swarm while they help Fran, but they insist it be the other way around. Surprised, Nora says Moriarty is old. Slightly offended, Moriarty says he can still fight and summons a sword cane and a chain that drags around a huge coffin. He says the coffin has everything: machine guns, missiles, and antimatter photon cannons. It is his ultimate weapon, The Dynamics of an Asteroid. He opens the coffin and it fires a blast that destroys one of the Geist. Nora is amazed, then Holmes summons a chair, several mechanical arms, and several lenses that focus on the Geist. He explains it is his Noble Phantasm, "Elementary, My Dear", which lets him analyze opponents and find out the best strategy to defeat them. Nora leaves to help Fran.
Fran clashes her mace against Other Fran's mace. Other Fran boasts that she is superior and will kill her so she will be the only one. Nora warns Fran to look out, and Fran jumps to the side as Victor tries to shoot through Other Fran to hit her, and Other Fran falls over dead. Victor frowns and says he should have known that trick wouldn't work twice. Shocked, Nora asks how he could kill his own daughter. He says neither of the Frans are his daughters, they are just monsters. As Fran starts to cry, he rants that when Fran was born, she released an electrical surge that killed her mother/his wife. Nora is horrified and realizes that in all their talks, Fran never talked about her mother. He did his best to raise her as a final favor to his wife, but then he concluded that she was nothing but a monster. He then shoots Fran in the gut.
Enraged, Nora attempts to attack him, but Fran holds her back. She speaks in English and says she did her best to be a good daughter, but then he left her all alone. A Geist enters Other Fran and revives her, then Victor says he was empty ever since she was born, and once she is dead, he will finally have peace. He aims his gun at Fran's head, but Nora darts in and chops his arm off, saying Fran is a good person and he is a crappy father. She tries to finish him off, but Other Fran blocks the Skewered Plasma Blade with her mace and they fight. Fran looks at Victor thrashing around clutching his stump in pain and moves to crush him with her mace, but she sees Nora fighting Other Fran and says Nora is her friend, then attacks Other Fran.
Nora slashes Other Fran in the back. The Geist inside her dies and she starts to fall, but another Geist immediately enters her and revives her again. Nora looks up to see Moriarty and Holmes mowing down all the Geist and realizes Other Fran can't be defeated unless all the Geist are destroyed. While she is distracted, Other Fran smacks her with her mace, knocking her through the air and breaking her Aura. She gets up and sees the two Frans fighting. Other Fran tries to trick her by imitating Fran's grunts, but Nora stabs her and says she can't fool her.
As another Geist revives Other Fran, Fran staggers because of her gunshot wound, and Nora says they have to end this quickly. She asks Fran to lend her power, so Fran zaps her with electricity that she absorbs. The Skewered Plasma Blade becomes huge, then she leaps up and strikes Other Fran with it, which completely vaporizes her body. Just as the two celebrate, Victor, holding his gun with his left hand, shoots Nora in the back and she collapses. Fran catches her, then enraged, she rushes Victor and beats him to death. Nora calls out to her, so Fran stops and cradles her, begging her not to die, but to her surprise, Nora's injuries heal and they hug.
A Geist enters Victor's body and revives him, but before he can do anything, Moriarty and Holmes walk up and Moriarty blows him up with a missile. They remark they finally got all the Geist. Moriarty grudgingly thanks Holmes for reminding him he still had a Command Seal since he didn't use it during Round One, which he used to heal Nora. They watch Fran and Nora hugging and remark they are like sisters. Moriarty flashes back to the day when Victor abandoned Fran. She cried and huddled in fetal position until he reached out to her. He says everybody needs someone and approaches them. Fran happily calls him Papa and the three hug. Holmes smiles and says he can agree with that.
