That's probably my main issue with that season story-wise (aside from there being no story at all). Surely a powerful supe that was hyped up for what, 2 seasons on a separate show, that can control blood is their deus ex machina to stop Homelander 2.0 by taking the V out of his bloodstream? Nah, we'll just speedrun the creation of a new superweapon that had no prior mention (of it being an option to make one, obviously Soldier Boy had it).
And if not, why were they even in that season for 2 identical scenes all they've done were sitting down listening that they shouldn't get involved... because surely Homelander wouldn't be able to reach them in Canada later.
P.S. Gen V are much better than the last 2 seasons of The Boys so, so don't feel too vindicated if you've chosen watching the latter over the former.
