Foreshadowing in A Study In Pink-
So I was going through screencaps of ASiP the other day, and I found this scene (that I had completely missed in the episode) that references directly to Reichenbach. The apple- I. O. U. and the mug- St Bart’s hospital, that Sherlock jumps off.
I have one thing to say.
EDIT: Guys, it’s been proved wrong- turns out it’s an RAMC mug, not from Bart’s. Damnit. Oh well. Until next time, Moffat.
