Wow, Lois definitely has herself in a pickle, doesn't she? And I have no idea how Clark is going to get to the police station by himself, let alone talk to the police without his secret getting out. Especially since -- maybe? -- the police seem to be taking their orders from someone else? Not sure who the mysterious conversation was with but I'm sure we'll find out soon. Things are getting more and more complicated for our heroes!
You asked for things that didn't quite sit right, though, and I had two that jumped out at me:
1) Did I read it correctly, that Lois has her hands cuffed behind her back for hours, even while they are questioning her inside the interrogation room? That wouldn't happen in the US, at least not with this kind of crime and this kind of suspect. I can see them putting the cuffs on her during the ride to the station, as they did in the previous part, but they wouldn't keep them on her while questioning her inside.
2) Lois is a complete idiot for not calling a lawyer after she's been arrested.

It's one thing not to bring in a lawyer if you're just being questioned -- it's easy to go with the "I'm innocent and all I have to do is tell the truth and it will be fine" mindset -- but if she's actually been
arrested, then this isn't them just fishing for information anymore. This is serious business, and she should know better than to assume that the truth -- especially the limited truth that she's able to tell -- will be enough. That said, I know this plot device is somewhat integral to your scene, and I do like the conversations Lois has with the detectives when they are implying Superman is an accessory, especially when she points out all the holes in their theories. I just don't think, procedurally speaking, they would arrest her without questioning her first. An actual arrest is supposed to come at the end of an investigation, not at the beginning of it.
Hope that helps. Looking forward to part 5.
