This is an AU where all eight kids have made it to a meteor in the Alpha Kid session that rivals the size of the ectobiology meteor belonging to the trolls and functions similarly, and Feferi has used her powers to revive all the dead Alpha-timeline trolls and their dream selves from BOTH sessions. Yes, even those whose bodies don't exist anymore. They're alive too.

CG: DAMN IT KANKRI.

Karkat stepped away from his computer, more than a little annoyed at his ancestor. He loved it when the Signless preached, but when he meets the Signless as an awkward post-adolescent troll, he suddenly couldn't stand the guy anymore. At first, he thought the lectures were just Kankri getting excited at the sight of his descendant, which was true, by the way. But it started to appear to Karkat that Kankri was trying to spite him. Why did Karkat have the inability to absorb a word that came out of that arrogant, insufferable prick's mouth? Oh wait, he just answered that: because Karkat believes Kankri is an arrogant insufferable prick and absolutely hates him. Right?

Karkat stares at the still open chat window a while longer before finally closing it, logging out and walking to the transportalizer into the common room, then taking the transportalizer to his side of the lab. He hated it because now his icon was a bright, mutant candy red; that very colour he'd been trying to hide for so long, and then Feferi brought every alpha player back to life. EVERY. GOD. DAMNED. ONE. Even the people who didn't have bodies anymore. Kankri had insisted on Karkat wearing his symbol in red and hemotyping, but he drew the line at both of those things. So, naturally, Karkat assumed that Kankri would want to lecture Karkat on hemophobia once again.

"Karkat, there you are." Once again, he was wrong.
"I've been meaning to talk to you about this for some time, Karkat. It is an incredibly sensitive issue and there are thousands upon thousands of things that could go wrong, and there are so many triggers one could name that I could possibly run out of breath if I mentioned all of them, but I think I should mention them anyway in the hope that it will at least help you understand." Kankri opened his mouth to speak again but Karkat held out a hand.
"Before you go any further, I want to know what the hell this is all about. I can't be every-fucking-where at the same time you know and time is rather strained for me. Lots of leader duties to attend to, so please make this the quickest fucking lecture you've made. Your personal best is two hours."
"Karkat, I am extremely triggered by your impudent remark, and I would much rather you desisted from such comments while I am trying to speak with you, especially since we are in this current predicament which is very nerve-racking and for me and is also causing me a great deal of anxiety which I would much sooner rid myself of, whether by a positive or a negative response. Now if you would allow me the time to speak, I would like to make myself clear to you. I am not trying to trigger you. I have no intention of making you fill buckets with me, and I have no intention of making you yell at me. I would like it if you did not react so negatively that you would force me to hate you, because as far as I am aware, we have a rather unstable relationship as it is, and I would not like for you to ruin it by getting over-aggravated about nothing." Once again, Karkat held his hand up to silence Kankri.
"For the sake of all things freedom, will you stop ranting and just get to the fucking point? This is seriously getting ridiculous! You've already spent the last five minutes rambling about nothing!"
"I do not wish to disgust you with the idea just because I'm your ancestor, but it won't stop me in the long run. I do not wish for you to beat me within an inch of my life because of said disgust. I'm not asking for you to comply to, or even to accept this. I just want you to hear me out just like so many others did the Signless so many sweeps ago in your timeline. In the hundreds of sweeps that I've spent observing my post-scratch self and then you, I have come to a revelation. While your ancestor has spoken through words, portraying his rage with daggers of the voice, crossing the line to the bitter end for an honest cause, you have done all that and more through your actions. You have let your rage control yourself for most of your life, and I will admit that as the sweeps went by, I actually felt sorry for you. You didn't need to suffer through all that you did just because your ancestor was unsuccessful in his attempts. You didn't need to live in fear of losing your friends just because of your blood. Everyone knows it now and nobody minds. Least of all, me." Karkat held his hand up again but this time, words failed him. He blinked, lowered his hand and looked down at his feet. He honestly had no idea where this was going, because none of Kankri's lectures went this way, and quite certainly, none of them this interesting. Karkat was actually paying full attention to what Kankri was saying, pulling it apart all he could for a hidden meaning. All he could detect was that Kankri wanted to be friends. Friends, he could do. He looked back up at Kankri and waited for him to continue.
"I don't want to offend or disgust you, Karkat. I suppose we're beginning to approach the crux of the matter. But I don't know if I want to talk about it anymore. You've been silencing me several times through our conversation and telling me to get to the point. Your violent tone is actually drawing me away from the subject matter, and that actually upsets me a little. You wouldn't know what that's like. You wouldn't know what it's like to really want to tell somebody something, but you were afraid they wouldn't look at you the same. Not even when we share the same mutant blood." Kankri's voice began to crack and a single tear rolled down his cheek.
"You don't know what it's like... to be flushed for someone who could never return your feelings in a thousand sweeps." Kankri spoke no more, endless tears streaming down his face. Karkat knew this was bad; Kankri never cried. EVER. He took the word of all eleven of Kankri's friends on the fact that Kankri at least never cried when anybody was around. Karkat pondered Kankri's words for several minutes.

I don't want to offend or disgust you.
There are thousands upon thousands of things that could go wrong.
It's too significant of a fact to talk about on chat.
I do not want to disgust you with the idea just because I'm your ancestor.
You don't know what it's like to be flushed for someone who could never return your feelings in a thousand sweeps.

When Karkat looked back at Kankri, he saw that the man had dropped to the floor, still the crying mess he was just moments ago. Karkat realized exactly what Kankri meant. He knelt down by his sobbing ancestor and brushed some of the red tears from his eyes.
"I'm not scared of how you feel, Kankri." He said simply. Kankri looked up suddenly to make eye contact with his descendant.
"I just need some time to think on it, that's all." With that, Karkat ruffled Kankri's already messy hair and left for his room.

Kankri watched Karkat leave. The same words kept echoing inside his head.
Do I actually have a chance with him?
