• Einstein and Tesla brought Theresa, Himeko, Mei, and Bronya to the Eye of the Abyss and explained that a prior Sea of Quantum experiment had failed and left someone lost inside.

As the Sea of Quantum’s brief stable period approached, Bronya took Rosaliya and Liliya outside to play near Abyss City.

• Kiana and Fu Hua reminded Han Jiang of his claim during the Valkyrie exam that Durandal was pursuing him, then suspected his connection to her as the group detoured toward Abyss City.

• Rosaliya told Bronya that Cocolia’s experiments had saved her and Liliya after they were badly injured, and explained that she stayed to help protect the orphanage children.
• Bella said she distrusted Rosaliya and Liliya because she sensed Honkai Beast auras within them, and Kiana reassured her that they would not hurt her.
• Han Jiang’s group returned to the Hyperion, where Mei welcomed them and Kiana eagerly hugged her.

Bronya struggled to reconcile Cocolia’s past love with her attempt to control Bronya, and Theresa helped her accept that she could not ignore the harm it might have caused. After returning to the Hyperion, Han Jiang’s communicator began emitting static that changed with his position.

• Tesla and Einstein finished calibrating new armor for Mei and Bronya, and Einstein told Bronya that Welt Yang had stayed in the Sea of Quantum to fight an unknown enemy.
