Seeing the 'Act 1' on the title already makes me excited since it's like a promise for a part 2. This time around tho, we get to see Sherlock's living condition. It's fun seeing his banter with Ms. Hudson and Watson, and once the pin drop, we finally get to see how it feels to be on the other side seeing Moriarty's handy work. This episode is definitely fun, and that ending makes me excited for the next one, hoping to see the other side of the case too!
