Personal topics:
“Completely linking with Veda”
“Bonds with the CB crew”
“Confronting Ribbons”
The golden-eyed Tieria in the OP is the image of Tieria revived in Veda after Ribbons killed him.

In addition on P9 about Sumeragi:
“She was feeling guilty about not noticing pretending not to notice Billy’s feelings. But, thanks to the power of Trans-am Raiser, the barriers between their hearts were melted.” {whoops, missed a word earlier}

P10 Feldt
Impact phrase: “She’s quietly waiting for the person she loves”
According to the article, Setsuna is unaware of Feldt’s faint feelings [for him?], and Feldt no longer has any special feelings for Lyle.

P12 Picking up Kati and Patrick
New info below:
• When Kati challenged A-LAWS’ armada in battle, her adjunct was Ash who had participated in the elevator coup d’état with Hercule.

In Patrick’s article, “Sacrificing his machine, he protects Kati to the end, but his machine took serious damage” “Is this the end for him?” and so on. As we suspected, it seems that he’s alive.

P14-17 Explanation of the 4 Gundam’s final-battle gear
Same stuff in other magazines this month.
New information about the O-Raiser on P14:
{paraphrasing: You need a person in O-Raiser because the Trans-am Riser System requires delicate tuning/adjustment to work at maximum efficiency. And that’s why they need Saji in O-Raiser.}

P19-23 Explanation of the A-LAWS and Innovator side
P20, in Billy’s article, new info:
• Billy developed the Gaga {no shit…}

P21 An article on Ribbons
• He’s the one that according to Aeolia’s plan was meant to guide humanity to Utopia after they’d awoken as Innovators.
• Ribbons and company were living in Celestial Being, the colony which contained Veda designed for space travel.

P22 an article on Regene.
Impact phrase: “The Innovedo who was waiting for the birth of an(the) Innovator(s)”

P24-25 Article on Regnant and Susanowo
According to this, during episode 24 while Louise [in] Regnent was fighting the 00-Raiser, [she] had taken serious damage from the Gaga suicide squad.

P26 All sorts of topics
“Innovators and Innovedo”
According to this, the Innovedo are beings certainly meant to guide humanity and to mimic the appearance of the reformed, new breed of human “Innovators.”

“The miracle of the GN Drive”
GN particles help to cultivate greater mutual understanding. They dissolve people’s reservations, and has become something that will hasten the end of war.
