Sober Companions

Liked this one. Finally got the payoff for this season's foe's actions, and they don't disappoint. It's nice to have Holmes have a main rival throughout a season. We haven't had one since Moriarty. Also, this foe is a mirror to Holmes, but a different way than Moriarty. She was on the same level of his intelligence and way of thinking. This guy represents Holmes' addiction and need for stimuli.

I do have a little issue for the killer here. He comes off appropriately creepy, however the actor comes off as one note in the way he talks.

Finally the show has started the Sherlock vs Villain of the season rivalry this early. I must say that I got S1 moriarty vs sherlock vibes from this episode. If they keep developing this rivalry per 2 episodes then it would be a memorable one. Don't miss this episode.
