While Buccaneer, Ed, Al, and Falman get the fuel ready, Olivia has her tanks push Sloth into the nearby elevator, sending him to another level. There, they pour the fuel on him, and their combined efforts are able push Sloth outside into the cold. Thanks to the vaporization qualities of the fuel along with the blizzard, Sloth completely freezes. In the aftermath, Olivia decides to have Ed and Al locked up, and Miles is tasked with going to see the injured Kimblee concerning Scar. Miles wants Kimblee to leave looking for Scar up to them, and since Kimblee still feels that the Ishbal Scar is his prey, Miles reveals that he himself is of Ishbal descent and that Kimblee should just stay quietly in the hospital. However, after Miles leaves, Kimblee is paid a visit by General Raven who has brought along a doctor who can use alchemy. Meanwhile, Marcoh is continuing his study of Scar's brother's research, and May Chang explains some of the Eastern Alchemy concepts to him. It is in contrast to how alchemy uses the energy of the planet's crustal motion, and what bothers May Chang is that she sensed, particularly under Central, the energy of wriggling humans. Back at Briggs, Olivia takes Buccaneer, Falman, Ed, and Al with her underground through the hole that Sloth emerged from. After proceeding through the tunnel for a while, Olivia stops the group and has Ed and Al spill the beans about everything they know since they're now in a place where others can't hear them.
Once she's heard everything Olivia asks about the tunnel, and Ed theorizes that it circles around the entire country. Building on this, Ed gets Falman to tell him all the major bloody incidents in their country's history. Connecting the sites of those incidents on a map draws a transmutation circle that resembles the one found under the Fifth Laboratory, meaning that their enemies are trying to create a Philosopher's Stone by using the entire country. What's more, all of the incidents can be connected to the military, so their enemies had created this country from the beginning for their own purposes. Hughes had been killed after figuring this out, and Ed realizes that even Isaac had known. What pisses off Olivia is how the map indicates that Briggs is going to be the next hotspot, and as if on cue, a messenger suddenly shows up with news that Raven has arrived at the fortress. Given all this, Olivia and the brothers decide to trick Raven. Having assigned Miles to show the healed Kimblee around, Raven meets privately with Olivia, and she tells him about Sloth, only she pretends to think that it's a biological weapon from Drachma. She also pretends that the Elric brothers refused to say anything and were locked up, and she claims to not be able to torture children. Olivia uses this to segue to her desire not to grow old and to the idea of an immortal body, and this prompts Raven to test her interest in an immortal army.
