The official photo of the series guaranteed a dark and emotional Sherlock season 4 to watch out for in 2017.

Anticipation is high for the premiere of Sherlock season 4 after two years off the air. Plot details revealed early on the possibility of Watson and Mary as parents. Amateur footage from the set last April also showed Holmes with a dog. Yet the lead characters would also face danger threatening to change their lives. Thus, it would coincide with the various clues from showrunners and Benedict Cumberbatch about its darkest and intense season to date.

1. New Villain

Cumberbatch, who reprises his role as Sherlock, teased the return of an old enemy. Moreover, he hinted at the entry of a new yet darker villain.

2. Mrs. Hudson’s change of heart

Mrs. Hudson has a bit more attitude this time around. In the trailer for the fourth season, she revealed what she thought of Mycroft. It comes right after she told him to leave her house.

3. The Game is over?

Typically, it should be the game is afoot. Thus, the tweet of Mark Gatiss and its caption would be unnerving. Fortunately, the words “for now” come after.

The first photo of Benedict Cumberbatch and Martin Freeman in their respective roles hint at big changes. Both sport a more mature look yet each with their distinct style.

4. Freeman as Watson

Watson sports a plaid shirt with a sinister hue. Moreover, his pose looking away from the camera with a bit of angst is certainly very different from the season 1 pic.

5. Cumberbatch as Sherlock

Like Watson, Sherlock revealed a distinct new look. Buzzfeed noted the characteristic furrow of his brow. Yet it would appear to be more severe than before. Thus, it might indicate the intensity of season 4.
