I think the thing was that Millar implied they were in love without drawing a fucking picture. Loeb not only stated they were in love, but had Wasp voice the "And what's wrong with that, Cap, you old square" comment which was simply wrong, along with implying that they were in love and also physically intimate, which even Millar had skirted away from. It's something that worked better as subtext and for the life of me, I don't understand Loeb's motivation for writing that scene at all, yet alone the way he did it.
