Cloud being a couple weeks pregnant with Sephiroths baby(ies) at the time he tells Zack that he won't be able to have any kids with him makes that scene hit even harder. Two bombshells dropped on Zack in a single moment.
That slimy bastard (and Shinra) fucked Cloud up, got rid of any sense of choice regarding his sex life and who hed want to have kids with, AND slipped right under Zacks nose and got his way with his fucking boyfriend, who's now carrying HIS child.
This is the longest and most serious relationship Zacks ever had in his life, and Cloud is one of, if not THE most important person to him right now. And Sephiroth is breaking him into little tiny pieces right before his eyes.
Zacks going to have a fucking conniption. He hasn't been this mad in a long time.
He's learned to read Cloud pretty damn good over the years, and as he looks over at him, he sees the fellow anger towards Sephiroth and Shinra in his eyes. But he also sees embarrassment. Zack just wants to hug and kiss it all away, but he knows it won't work. All he can do is be the best godamn boyfriend ever.
He knows damn well Seph isn't gonna come down and take care of the omega he got pregnant so HES gonna fucking do it.
He's gonna raise the kid right, too. That's HIS baby now. Whatever Sephiroth has to say about it can go in one ear and out the other. Like he ever gonna let Seph get that's close again, anyway.
(This was originally going to be much shorter, and written more like an ask but I cooked too hard, and now I don't know what to do with this, so I'll just send it anyway to see what you have to say 😅😂)
Nah, make it that he's a couple months. Just far enough along that he's just starting to show if you look closely. So there's already that visible reminder of exactly what Sephiroth (and Shinra) have done to him.
That's honestly the biggest thing driving Zack's rage about it. The fact that the choice has been taken away from Cloud. Like, yes, he'd love to have kids now that he has a happy relationship with someone he loves but one of those things you risk when you sign up for questionable science done to your body with the exclusive goal of being made stronger is that there's a risk it'll make you sterile (and also probably die young). He agreed to those terms so while it might suck he chose it.
Cloud however didn't chose to give Sephiroth exclusive breeding rights over him. And like seriously Hojo - what the fucking hell!?
There's also definitively guilt there because Zack's the reason Sephiroth (and Hojo's) attention was drawn onto Cloud in the first place. And in this set-up probably because of Zack and Cloud starting to date.
Which at least he channels the guilt in being the best damn dad to this kid. Because, yeah, he sure knows that Sephiroth isn't going to do it (nor would they exactly want Sephiroth to do it considering his ideas of parenting are likely with the goal of just creating a mini-version of himself). And at least this way he can still have a kid with Cloud (and also like he's not exactly going to just leave Cloud so he's going to be around the kid anyway.
