Boom, Headshot!: Gihren gets a neat whole blasted through his head by a vengeful Kycilia, a direct consequence of Gihren having killed their father not long before.
Technically Degwin Zabi is only confirmed as gone this week.
Damn You, Muscle Memory!: Zeong not having legs means Char's famous flying kicks are out of the question this time around.
Dramatic Irony: Char realising the Zeong isn't drawing out as much as ability as he should have is oddly similar to what Amuro was just going through with the Gundam.
Surprisingly Realistic Outcome: Turns out no matter how advanced the mobile suit is, if the pilot is a total newbie and not a newtype, they will not last long. Kycilia learns this the hard way as even with the Gelgoog being technically superior to the Gundam, almost all the pilots they have left are freshmen.
Unfinished, Untested, Used Anyway: The Zeong, famously enough, as it didn't even have its legs attached (and one Zeon mechanic had the gall to claim it wouldn't need legs.) One Mobile Suit Variation, Perfect Zeong, generally shows what it'd look like with legs attached.
