Char extricates his body from the gaggle of crying children now they stopped attacking him, his pants were lightly armoured so they probably hurt themselves more than they hurt him. This is incredibly awkward.

"I was just looking for Sayla... So if we are done here I will... Just go keep doing that?" It is very hard to keep the appropriate level of gravitas in a situation this strange. Going from violent tension and veiled threats to dealing with children was definitely not something he had practice at.

Sayla is helping Amuro nerd at the Zeon mobile suits help Char's soldier's with the ammunition issue which just goes to show you should never split the party.

Before Char has a chance to figure this out, Kai and some of the others will find Bright whose whereabouts are known. They just barely have the sense to put up their weapons first.

Because Kai is their brave leader convenient fall guy if this goes south the mob lets him go first.

"Hey Captain we have some questions about Char."

"I have some answers. They might be the ones you're looking for."

"He claims that he's actually been against Zeon from the start as some kind of double agent except not actually working for the Federation either. Also that destroying Side Seven was against his orders."

Good he was expecting either this or for them to start questioning his decision to allow Char to stay on board and he didn't want to have to make an example of Kai for insubordination.

"I have independently confirmed that he has a grudge against the Zabi family that predates the war, and deliberately killed them. I don't have direct information on what orders he gave at Side Seven, but it fits with what else I know. Char wouldn't be walking around my ship if he was a Zabi loyalist."

"I don't like or completely trust Char, but we're stranded with him and he helped saved the Earth so we're cooperating as long as he is."

He doesn't say "thats an order" but it clearly is.

"Right that clears things up."

It's taken awhile due to his personality but Kai has mostly figured out when it is an extra bad idea to push Bright and the issue is clearly closed. The actual information is something he'll need to thing about.

Bright's very tempted to add that Char is where the money for his vintage glasses came from, but he doesn't want to cause issues for Sayla.

After the bridge has cleared out Mirai observes:
"At New York, we only survived because he wanted Garma dead."

"Probably."

Char is now much more careful about avoiding people in the halls while he looks for his sister, he doesn't find her anywhere, so he gives up looking and heads back to the mobile suit hangar to meet up with his men and warn them about angry feddies.

Oh! Theres Sayla’s recognisable blonde hair! ...and also recognisably curly brown hair belonging to Amuro. Char very much doesn’t want to talk to Amuro right now, its been months but the death of Lalah still felt pretty raw. He wasn’t going to challenge him to a dramatic duel to the death that resulted in vengeance or suicide or anything, half a year ago he still might have, but talking to him outside of a professional setting would be too much for right now.

He just just sort of stands awkwardly by the entrance to the hangar, unsure if he wants to go over there. For the millionth time he is glad for his mask so he just looks like he’s mysteriously brooding instead of insecure.

Amuro doesn't want to talk for basically the same reasons and will pretend not to see him.

Sayla doesn't want to talk for only slightly overlapping reasons and will join in the pretending not to see game.

Char heads over to his comrades, who just happen to be near Amuro, but it’d be weird if he just left as soon as he saw them and didn’t speak to his buddies.

“Hey there captain. Looks like we will be able to reload our guns. But since this isn’t a proper ammunition factory they probably wont have the same muzzle velocity as the standard rounds. But who knows if the standard rounds would even scratch some freaky alien anyway.” The soldier chuckles at his own joke.

Another of the squad pipes up. “Wait we have to fight aliens? I don’t want to fight no creepy green men who can mind control you.” He looks nervous.

the first soldier smacks his comrade on the back. “Who else would we fight doofus! Ain’t no other humans out here, and you read too much old pulp, they probably have tentacles and aren't shaped like people at all.”

The bickering continues as the two others in the squad join in in arguing about what the aliens will look like, they are obviously a pretty closely knit group. Char does not join in, even among his own men he is a bit of an outsider.

“Glad we have the supplies to rearm, for... whatever's out there.” And more pointedly pretending Amuro and Sayla aren’t right there in front of him, 

Sayla is very good at the pointedly pretending game.

Amuro breaks. 

"Char do you have a minute? I have something I want to show you."

Char stops the grimace from crossing his face. It’d be weird if he refused.

”Okay.”

Amuro get ups and leads him to the break room. He hasn't exactly thought things through, but plans to ask him some of the same questions Friedrich had as a warm up to the really hard ones and has a vague idea of using the red Zaku as a transition.

The break room is mostly empty to begin with and clears out completely when Amuro and Char show up.

Amuro goes over to the model boxes and starts pulling stuff out until he get the red Zaku and puts it on the table. He pauses for a moment to collect his thoughts and see if Char is going to ask any questions.

“My old Zaku command type... It’s not badly done. It’s nice and all but you brought me here to show me a toy?”

Char was confused as to what Amuro wanted, why he brought him here. 

"One of the Zeons we left behind on Pluto made this. He had some questions for you, and since he's not here I'm going to ask them instead."

"Why did you do... everything really. Why did you fight for Zeon to begin with and why did you kill the Zabi's when you did? Why did you..." He was going to ask why Char got Lalah involved but isn't quite ready to go there. Also its not something Friedrich even remotely asked about.  "Just why."

Char locks the door to the room before answering. Then takes off his mask.

“I suppose you, my greatest foe, deserve to know.

My name is Casval Rem Deikun, son of Zeon Deikun the beloved prime minister of side 3. The Zabi family poisoned my father and twisted his ideology of Spacenoid independence into a call for war and Spacenoid supremacy, riling the people up into the coup that lead to Side 3 becoming the Principality of Zeon. Using my fathers name for their twisted abomination of what he would have wanted.

I escaped to earth as a little boy to avoid being used as a tool or assassinated myself, and swore I would kill them all. Once I was old enough I adopted the identity of a spacer drifter named Char Aznable and joined the Zeon war college until the war broke out, and then rose through the ranks of the Zeon army. Waiting for a chance to kill them.

Sorry for using you as a tool to kill Garma, but it was the perfect opportunity.”

Char may or may not have had the dramatic reveal speech mostly prepared beforehand. In case anyone found out.
He doesn’t mention he wasn't alone when he escaped to earth, his sisters identity is not his secret to share, and she obviously had a thing for the boy. He wouldn't sabotage her chances with Amuro, even if he still resented Amuro for killing Lalah.

Char is treated to the flattest "What" he has heard in his life.

Amuro doesn't know what he was expecting but that could not have been less on his radar if it was hiding behind every I-field in the solar system.

"Wait thats so crazy it actually makes sense. But do you have any proof, and why did you have to bring Lalah into the war. Also why do you look like Sayla?"

“I uhhh... suppose a DNA test would show proof I am the son of Zeon Deikun. I cannot imagine his DNA wouldn’t be on record.” And there was enough of his father in his face that a look at a photo would be convincing enough, he wore the mask for a reason.

“And Zeon Deikun had two children who fled to earth. Anything else about Sayla Isn’t my story to tell.” Fuck, Amuro could tell just from their faces, sorry Artesia.

“And Lalah... I found her in a brothel in india, I could tell immediately there was a newtype nearby she was that strong. She started travelling with me and I handed her off to the Flanagan newtype institute before I was sent to spy on the Federation mobile suit program. When we met again she was even stronger, almost too sensitive to whatever it is newtypes are sensing for her to handle. I was distracted from my revenge by the potential she showed as a next step for humanity. Perhaps my fathers beliefs influenced me in that, I became obsessed with the idea of humanity reaching that next step.

Then Kycelia found out who I was and I agreed to keep serving Zeon as long as they kept pushing forward research of newtypes, I put aside my revenge for that goal that was so clear in my mind. Lalah was grateful to me for rescuing her and wanted to help me fight and show the Zeons the power of newtypes so they would continue the research.

And well... you were there for what happened next, Lalah died, I wanted revenge on you, then Sayla reminded me of my original motivations at A Baoa Qu and I left to go kill Kycelia. Then the war ends and nothing much happens till my men get called in to this superweapon.” He's had a lot of months to think over what happened and put all the pieces together. He doesn't know what took him over back then, he was so convinced about newtypes that he set aside his revenge for them, and now it seems a hollow goal.
