I love making memes that I specifically (and maybe 3 more people) find funny.

Did anyone ask for more Cletus/Red smut? Probably no, but here's some anyways.
Look at how happy Red is. Awwww :3
Cletus and Frances: [*Planning their honeymoon*]
Carnage: So... where are we going?
Cletus: ..Look Red, this has nothing to do with you.
Carnage: That's impossible!

[Carnage, remembering Eddie bitching at Venom and generally being a selfish dick and completely ignoring his partner's needs...]
Carnage [realizing]: Oh no.
Carnage: I've become my father. My human father.
Carnage: Fuck, this is horrible.
Carnage: I've been trying so hard not to be like Venom that I did not see this coming.
[Later]
[Cletus and Frances waking up from their nap]
Carnage: Hey... uh, I got you something.
Frances: You ordered pizza?
Carnage: I thought you both might be hungry.
Frances: That was thoughtful.
Cletus: Shit, what if someone saw us--
Carnage: Oh don't worry, I ate the delivery guy.
Cletus: Oh. Uh, ...thanks?
Frances: So... what brought this on?
Carnage: I realize I haven't exactly always been... I know you, both of you didn't exactly agree to this... on my world we just take hosts and--Dammit, let me start again. No excuses. I'm sorry! I'm sorry I was rough on you, Cletus. I'm sorry for what I said to her when I was in pain. I realize I've taken you for granted. I'll try to be nicer.
Cletus [exchanging looks with Frances]: Oh. I... that's... that's... good? I think?
Liveblogging reading Carnage comics
From Webspinners Tales of Spider-man #13-14 Carnage Classic trade paperback
Spoilers/Context: Venom ate the Carnage symbiote but unlike in the movies not Cletus because in 616 Venom doesn't usually eat people. Like he will sometimes but it's not like a typical thing. Honestly in the comics Eddie is the more murder-happy of the two of them...
Cletus finds an identical Carnage symbiote sealed away in an Eldritch tomb in the Negative Zone that he heard calling to him from across universes.
This feels like it should have been a bigger deal then it was, as it's just tucked away as a B-plot in a side story.
Like, how did that get there?
Could it somehow be connected to Cletus messing with the Darkhold in the later Carnage 2016 storyline or the Carnage symbiote's current attempts to obtain godhood?
The Eldritch horror-terror implications of a possibly time traveling weakened eldritch God Carnage symbiote being sealed away and still being able to call Cletus from a universe away are, again, just tucked away in this side story...
Also in this story Mary Jane seems to have died in a plane crash? Like wtf? Except she didn't?
Okay, a quick google search explains MJ isn't really dead because she wasn't on the plane but she was being stalked and kidnapped and Peter evidently didn't notice anything amiss.
So... quick recap.
Cletus hears his alien spouse calling to him from across universes.
Peter fails to notice anything going on with his wife.
Wow. That's... not a good look buddy.
Like I'm sure Peter had other stuff going on as always but that he'd be completely oblivious to that? Didn't even notice his wife was upset or anything? A case of poor communication or just bad writing?
Cletus: Yes! I got the tickets!
Frances: Awesome, baby! You're the best! We can finally see them in person!
Carnage [grumbling]: Why does everything you love involve blowing out our eardrums?
Cletus: No one's making you come.
Carnage: Please... You'd get yourselves caught or killed in five minutes without me.
Cletus: You know I killed quite a few people before I ever met you, right? We're not exactly helpless...
Carnage: I think you're buying into your own hype. Your instincts are not as sharp as they once were, are they? After years of decaying, rotting in that cell. Do you want to go back there? Cletus, you need me.
Cletus: ...Tell you what, buddy. I can already see if we take you along you're gonna bitch the entire time or massacre the band and the concert goers and generally be unpleasant during our date so how about you stay here tonight? You can spend a peaceful night eating cops by your lonesome and Frances and I will have our date night at the concert. And it will be fine.
Carnage: Without me you are squishy and vulnerable to bullet fire. And what if some little hero crashes your date? What if my father finds you?
Cletus: Well then... Frances can protect me--she's a badass in case you haven't noticed. Assuming I don't get him first. You know...
Carnage: [*sulking, going into her cat as a temporary host*]
Carnage: You need me.
Cletus: ...maybe I do. But I promise you we'll be fine for one fucking night.
Carnage: Fine. Don't die.
Frances: Jesus, we're going to a My Chem concert. Not off to war. It'll be fine.
Carnage [snarling]: Take care of him!
Frances: Of course I will, he's my husband! What's gotten into you?
Carnage: What's gotten out of me more like it. Pardon me for being concerned about my host putting himself in danger...
Cletus: You just really like my body apparently.
Carnage: Yes I do.
Cletus: Ah...
Frances: ...See you later, Carnage.
