some ep11 predictions that has been in my head. this is the most plausible scenario.
> A plot - Yomagn'tho firing chamber
Machu and Nyaan talks about while fighting, the former mostly evading and the latter going for the killing blow. Nyaan loses her shit and goes berserk like Machu would've been in ep7 and overpowers GQux temporarily, allowing her to reveal the 2nd coordinate and attempt to fire again. Machu recovers, activates GQux's hidden armaments, and goes back at Nyaan. Some condition is triggered and Shuuji manifests inside the chamber alongside Gundam. Gundam, Elmeth, GQux, and GFred react to each other and causes some weird shit, which the episode ends on. Yomagn'tho's structure likely collapses as a result
> B plot - living quarter
Kycilia tries to make her villain speech but is killed by Char in uniform at some point. Char makes a public appearance, revealing his goals and probably his whereabouts after getting teleported. It probably happens mid-episode and affects other plotlines.
> C plot - outer space
Challia engages Xavier & co, destroying or disabling the purple Gyans along the way. He holds off from killing Xavier and instead the two talks. Intentionally or not, Xavier kills Challia when the latter is vulnerable for some reason, likely distracted by Char's presence. Xavier then makes his way to Yomagn'tho but won't get to the core. Sodon might engage Kycilia's fleet and/or attempt to breach the weapon though the latter is more likely. It or its lifeboat will be the only survivor by ep12's end.
