This isn't the first time..
What's your opinion on Joanne Woodward?
I'm seeing an excess of defenestration in A Scandal in Belgrade.
Irene Jumped out a window escaping her flat, and Sherlock threw the CIA guy out his window several times, while he was seeing what could muffle a human splat, which apparently are not Mrs Hudson's bins well.
Almost like Sherlock is planning something for down the line.
