(I accidentally deleted the first draft of this, so if this doesn't read that well, that is because I am... Frustrated.)
Carmine wasn't sure that he should even be here. He wasn't sure why he was here, either... Topaz had something written down about being here at this time, so he had come. He sort of guessed this had something to do with their job, and maybe he should have just had them reschedule because he knew next to nothing about that, along with being mute in general... It was too late now to go back, so now he was following a stranger to what she said was the lobby. He stared down, obviously anxious and shaky. He hoped that his brothers would be proud of him for being here, though it was more likely they'd just tell him not to do this sort of thing again... He didn't blame them, though. He looked over to the stranger, and stared at her big jacket. It looked pretty cool, actually, though it didn't fit her at all.
When she started to talk, he seemed even more anxious. She was being vague... He didn't like vagueness. Out of those first few sentences, only one word stuck out to him: danger. He didn't like danger, either. Now he really wanted to go home... He didn't know how to respond, so he just kept quiet, hoping that eventually, he'd get to go home... Until the girl stopped and looked at him. He looked back at her, eyes filled with anxiety. What was happening? She then explained that she was going to let him in on a secret, that she wasn't taking him to the lobby, and that she was instead taking him to a computer room because he looked like someone who could help... Oh no, now he was sure this was a mistake, because this only scared him more. He tried not to just sit there and cry as she smiled and continued on, talking about stopping the madness of the world, needing all the help she could get, being a spy for a detective girl, and getting intelligence from him. He stared at her, wide eyed, before signing, "I'm really sorry, I don't know anything about this. Is this meant for one of my brothers? I can't talk with my voice, much less have any intelligence. To be honest, this is scaring me a little, I'm really sorry. I can write down in our journal for them to come talk to you later, if you want, I just don't know anything." He shakily grabbed his journal from a secret pocket in their tailcoat, wrote down everything he had signed, tore out that page, and gave it to her, just in case she didn't know ASL.
Carmine stared at the person in front of him, shaking a little. He contemplated if it was really a good idea to talk about something like this. What if they used it against him or his brothers, or used it as an excuse to hurt him? But, this person seemed to want to know, so he shakily started signing, "It's no secret that I can't talk with my voice. If I could talk like that, I wouldn't be signing to you right now. But, my brothers can. I don't know why they can and I can't. It hardly makes sense to me, so I doubt it'll make sense to you, but, the secret is, my brothers don't have bodies of their own. We all live together in one body. There's no real 'White', we are all White. We rarely talk about this, but, you seem okay? Maybe? If you're not already thinking I'm weird? But, like I said, they can talk. It isn't because the body's vocal cords are damaged, but, my mental ones are. There's a disconnect there somewhere, and sometimes, I feel bad because I feel like if my brothers can talk, I should be able to, too, but I can't. I usually only talk to Sanguine about this, but, you're not going to tell anyone else, are you? You're my friend, right? Maybe not, but, I don't really have any other friends to talk to besides Sanguine, and he already knows everything, so, I'd like to be friends, maybe?" He slowly put his hands down and looked away. He wasn't too used to having to talk that much with his hands, but it seemed like the only viable option. That is, if the person even understood, or had focused enough to understand all of what he had said. If they hadn't, that was okay. It would be more difficult to use writing if they were to be friends, but just in case, he pulled out his journal and started writing an abridged version of everything he had just said, looking up at them for a moment to make sure that they hadn't understood so that he wouldn't waste paper.
(Because I sort of felt that I would kill the thread if I made him just say everything in ASL, if your OC doesn't know it, just presume that he finished writing that and gave it to your OC!)
Carmine had a small smile when the person mimicked his signs as they read. It showed that they were willing to learn for him, and that really meant a lot. He stared at them with a smile as they started to talk, giving them small nods with every few words or so to show he was listening. His face went a little pale when trauma was mentioned, but he swallowed those thoughts down. His smile turned into a big and goofy grin once the word 'friend' was mentioned. Friend! He had made a real friend that wasn't Sanguine!
Once they were done, they grabbed the journal and wrote down another note which he passed back to his new friend. "We're friends now, right? Yay! But in response to what you said, I'll let you know if anyone tells me it's my fault. And yeah, DID, that thing! You're probably right about the cause, though... I'm the EP, which means I remember all of the trauma. It's... Really, really hard to sign, write, or even think about. I would appreciate your efforts and stuff, though! And it's so nice that you're willing to learn sign language for me, that makes me happy. Also, this is sort of off topic, but do you like insects? I think they're pretty cool! And I like your horns, too! They look cool on you!"
