Under the cover of night, Laura directs three Agathions to destroy Jin and Toa’s home, but fortunately they had already escaped. Yonamine Kou is sure that the ISDA will quickly figure out that the house was empty and come after them, so he decides to drive them to Tokyo. His reasoning is that it’s easier to hide where there are a lot of people. What’s more, their target of Tartarus is heavily guarded, so they need to prepare and get equipment. Kou knows that they have to go somewhere the ISDA can’t get them for the time being, and that place is the Baumgard family’s home in Japan. The first thing Toa notices when they get there and go inside is the painting of Amadeus hanging over the stairwell, but the butler informs them that this is actually Sieglinde’s grandfather Alfred. When Sieglinde’s father Wilhelm then comes out to greet them, Sieglinde acts coldly towards him and wants to leave. He is willing to hide them though, including his daughter since she’s the family heir, and he knows the ISDA won’t come here because the family has invested money in the ISDA.
Meanwhile, at the ISDA base, a scientist is telling Kazuki, Widow, and Sakaki about a newly developed anti-Thanatos factor that works like a cancer cell killing the healthy cells. When Kazuki asks how they’re going to place this in Thanatos, Sakaki explains that they’ll use dragons and compares it to tossing an infected mouse into an enemy camp as a biological weapon. It turns out that they’ve already started experimenting with Howling Star and Amadeus. Back at the Baumgard house, Toa asks Sieglinde how it feels to have a father since Toa has no parents. Sieglinde claims that it’s not a big deal, and though she admits that she wouldn’t have been born without him, she feels that she could live without her father. She thinks that he is only hiding her because she’s the heir to the family and that he cares for the family name more than he loves her. With her stigmata acting up, Toa then decides to go out for a little while and is spotted by Gio from the balcony above.
Around this time, in a snowy mountain range, Laura shoots down Otome and Itsuki, capturing them both of them. Kou learns about this when he and Yuuri talk over the phone, and she reports that they’ve been taken to Tartarus. Yuuri also finds it odd that there are people and machinery being taken there, making her think that the ISDA is doing something with the dragons. Before hanging up, she asks Kou how Toa is doing, but Kou doesn’t know of anything in particular wrong with her. Yuuri then returns to her hideout and discovers that the stigmata on Nozaki’s back are acting up. Though he’s in pain, Nozaki tells her that it’s okay and that it’ll subside soon. At this exact same moment, Toa’s back is also lit up, and Gio approaches her to question if it’s really okay that she doesn’t tell Jin. Toa doesn’t think that it’s time for him to find out yet, so Gio points out that there’s not much time left. Gio then senses something from Thanatos, but he tells Toa that it’s nothing and vows to protect her.
Having noticed that Gio isn’t around, Jin is looking for him around the house when he happens upon Wilhelm staring at a picture of a young Sieglinde with her dog Amadeus. Wilhelm tells him that Sieglinde’s grandfather loved this country and frequently found time to come here. Sieglinde’s mother, on the other hand, died sometime after giving birth. Wilhelm then reveals that he’s not actually here in Japan right now for a conference like he had originally told everyone. After he had heard that his daughter was being chased, he had suspected that she would come here, so he came too because he wanted to help her. Jin thinks that he should honestly tell her this instead of talking about her being the heir, but Wilhelm feels that she hates him, and he explains that she only ever opened her heart to her grandfather and to her dog Amadeus. Nevertheless, Jin makes a plea for Wilhelm to tell his daughter his feelings because they’re about to embark on a dangerous mission with no guarantee of a safe return. The two are then interrupted by Kou who reports that Howling Star and the others are in trouble, so they have to leave the next morning.
Over at the ISDA base, Sakaki is observing how Laura also has the stigmata on her back, and he comments on how convenient of a tool she is since he knows that she’ll die after they’ve dealt with Thanatos. When she turns to look at him though, Sakaki avoids making eye contact. He then gets a notice from a scientist telling him that the anti-Thanatos factor injected into Howling Star and Amadeus has disappeared due to immune reactions. However, they haven’t seen this immunological effect in their samples of the original dragons, meaning that the anti-Thanatos factor will probably only work in those original dragons. Thinking about this and looking at Laura causes Sakaki to start laughing uncontrollably. The next morning, at the Baumgard house, Wilhelm asks Sieglinde to come home with him as his daughter. Jin is ready to leave her there, but Sieglinde decides that she belongs in the Dragonauts and needs Amadeus, so she ends up going with them after all.
Isn’t it a bit late to be having a Sieglinde focused episode? I’d say it was a momentum killer, but there wasn’t much momentum to begin, so I guess that doesn’t matter. It’s just that, all things considered, this was a fairly weak episode where all the Sieglinde parts could have just as easily not been included. The reconciliation with her father was something introduced and concluded all within this one episode, and I doubt that I’d feel that I was missing out on much if they had just moved forward with the main story instead. They did accomplish that to an extent with the anti-Thanatos factor (if you’re confused about that, think X-factor from X-Men) stuff, but we’re at the point in the story where there aren’t a whole lot of episodes left, so I wish each of them had more exciting/interesting/relevant material. Having said that, the one thing I can think of to justify all this is that the Sieglinde back-story might be being used to build up her character so that if she dies, it’ll have more impact. There’s no indication that they plan to do that, but it’s always a possibility.
