Yikes.
The adults in the locker room didn't even ask Lois what happened. They obviously don't care that Tom assaulted her. Even if it boils down to a he said/she said situation, it should be documented that Lois claims that he assaulted her. The bruises on her neck should go a long way to support her claims. She needs to go on the record now so that, even if nothing comes of this incident to punish Tom, there's a documented history of him attacking her to support her claim the next time he does it.
Clark was smart to get Mr. Johnson before he intervened, or else he would be in serious trouble for fighting.
If Tom is currently suspended, why is he allowed on campus? Shouldn't he be in trouble for being there in the first place?
So has Clark been keeping a covert eye on Lois's place while he's out and about? How quickly will he get there to save her? (I ask this, of course, hoping that that's what's going to happen.)
I also get the feeling that Lois is not going to get any backup from the DP. I presume that Ralph is flat-out stealing her story. I admit that I don't have any real knowledge of how newspapers function, but it seems odd to me that Ralph finds the idea of an intern actually writing a story so preposterous. If she has done all the research for it, why shouldn't she write it? I can see that they would pair her with an employee to help her polish it, and maybe it would be a joint-byline, but why shouldn't she expect to do the write-up for the work she's done?
