"How do you know he didnt sneak up on her while she was fighting Wasp and Giant Man? You dont know for sure. But one thing you can clearly see is that is was 3 on 1."
The same way we dont see if he needed to sneak on her. Those two at such a low size are nothing more than an annoyance to guys at this level. The strenght and skill needed to pull that move was from him.
And we all saw how such an easy time she was having.
"The last person WW was seen to be fighting was Wonderman. And she knocked him out"
That was before Herk got her. We dont see him knocked out, since he was up when he attacked Superman.
Giant man started to go on her when Herk saw Thor down (and proceeded to attack him) by punching Wonder Woman. When the sea monster shows up to take the avengers out of Superman she was showed to still be figthing him and punch him. Three pages.
