Hi! I am new here. I am from Brazil so please forgive my english!
I read a lot of messages of this topic but I couldn't read everything, so I am sorry if I am saying something that someone said already.
I loved the episode, but I have some questions, I would be happy if someone could help me. I watched the episode at 5 am, so I if I am being dumb or something its because I was a little bit out of myself when I watched hahaha
1-Charles threatened Mary to get to Mycroft, right? So when this actually started to happen? Before the wedding or after? Anyway, Sherlock mentioned that Mary was friend with Janine just to get closer to Charles. Janine was at the wedding, so it's very likely that she and Mary were friends for some time. Charles must threatened Mary a long time ago, but how does he knew the importance of Mary to Watson at that time? Unless she threatened her when she was engaged and Mary befriended Janine very quickly, which I think it's possible but also a weak point in the plot.
2-What were the odds of Sherlock break into Charles office and Mary be there at the same time? Did I miss something?
