“Yes, Clark and I often take the stairs. After sitting at one’s desk for hours, it feel good to stretch one’s legs, doesn’t it, Clark?” Lois asked, seeking his approval, and knowing she would get it.
I am pretty sure that it should say "it feels good".
“Who do you think? The Pied Piper?” Lois said wryly, trying to pull her arm away. If she just get him to point that gun away from her, she could use one of her Taekwondo moves on him. “Superman, of course.”
I think it should be "If she could just get".
“Let’s just say that’s he’s always there for me when I need him,” she replied.
I think it should be "that he's always".
Superman? These cyborg boxers couldn’t hurt him, could they? Superman picked up one of them men and dumped into a pile of nearby trash.
I think that should be "dumped him into".
