DHGF: Cognition: An Erica Reed Thriller Episode 4 is the second best entry in the four part episodic series, the third I feel being the best but this part manages to tie up all the loose ends without feeling like that’s its sole purpose. Tying Erica and Cordelia’s abilities together and forcing the two to work together to get to their goals even though their goals put them at odds with each other was a great move. All the plot threads that were seeded throughout the other episodes and especially the third come to fruition here with a driving plot to this episode that really keeps you involved and wanting to see it all through. While I say it’s the second best entry, really that’s all because we know most of the details already so the investigation is just about getting around hurdles to get to your prey instead of discovering who your prey is. While it’s still compelling much of the mystery has been sucked out to tie everything up but this episode does this amazingly well so you’re not left wondering what will be.
