I wasn't sure where else to post this (opinion maybe?) as this forum seems full of word games but here goes. Anyone got any theories as to what the heck happened in the last episode of Sherlock? I've been mulling it over for the last couple of days and can't figure out how he managed to leap off the building and end up alive. My conclusion is that it is something dastardly clever, or (hopefully not) disappointingly non-sensical. I am sure it has something to do with Molly the lab girl, although I suspect she is unaware of the part she has played. The cyclist who knocked down Watson is also likely to be a part of the plan, but I don't see the rest. I don't buy into the theory it was someone else wearing a mask. It just sounds silly and, unless the medical staff were in on it he would have been found out during the post mortem. But I haven't got any better ideas.
