Some highlights include

Mustadio: Attempts and fails to get Alma to chill, talks smack about Wiegraf right in front of him, is generally a bro to Ramza, and confirms this by promising to beat Delita's ass in the event of his betrayal in the man's face.

Agrias: Is known to Zalmour who believes her to be deceived by Ramza, establishes the unfairness of the Fifty Years' War's aftermath with Wiegraf, establishes that the Lucavi can just make more Auracite to 'uplift' the masses with Belias, manages to wrangle Ovelia's continued safety out of Delita, and get's Hashmal to tell her of Ovelia's true origins

Orlandeau: is mostly very chill and factual with Elmdore, establishes that had he turned Lucavi his power would well outstrip Zalera, trades barbs with Dycedarg, gets to give words of encouragement to Zalbaag, puts Delita in hot water with Folmarv vis-a-vis his continued existence, and offers to mercy-kill Zom!baag in place of Ramza

Beowulf/Reis: makes his case to Folmarv, for all that's worth, who believes him, for all THAT'S worth. Establishes that the curse put on Reis, and what lingers still, put the soul of a dragon into her, giving her great power and memories not her own

Meliadoul: Is very much a refutation of all the Knight Templarate believe in, her interactions with Loffrey and Clentienne serve more to establish the depths of their faith in their cause, giving them much needed characterization.

Cloud: only has interactions with Folmarv, who offers us insight into how he came here: He didn't.

Cloud in FFT was copied and place into a flesh approximation created by the Auracite

he is described as an Aberration (charitably) by Folmarv, with Hashmal calling him the P word.

Cloud's Soul*

Rapha and Marach have not been uploaded, neither has construct 8, though I do hope he has lines

Yeah, the FF7 fans I'm with are talking about it
