Basically, the episode falls prey to allowing theme drive the plot.
Marissa tags along with Jay because shes interested in becoming an investigator, which is a welcome development.
Both of these lead Diane to realize that Neil was setting them up.

Diane calls Neil out on his BS, which ends up damaging her professional relationship with him.
Dianes victory at the end of last weeks episode was very short lived.
Once the panel is over, Diane finally lets out how she feels about the attention-obsessed troll.
It seems like the show got too caught up in the idea of doing an episode on internet trolls.
That being said, this case does have strong implications for the firm.
While all of this is going on, Elsbeth puts another plan into action.
The firm is in an unusually vulnerable position.
Although I didnt particularly like this episode, I am interested in seeing where this all goes.
