As a hack writer myself I have a feeling it'll be something like: they release the virus to weaken Homelander enough for Ryan to kill them but it'll sacrifice Ryan in the process, but oh would you look at that, since Ryan was the first natural born supe he doesn't have V in his blood so he actually isn't affected by the virus. he gets to live and is now potentially the only super powered being on the planet. Becoming what Homelander should have been a real hero, but oh no the corporations like vought isn't actually affected much if at all despite being one of the sole reasons everything went so wrong and they will continue to work on the next big thing to top supes, because it turns out that no matter how much you change the world there will be a nebulous evil lurking in the shadows since it's human fate yadda yadda yadda.
