Well, it '''is''' Franchise/SilentHill...


* All of the John-a-likes to some degree; they all think that they're the real John. What about [[spoiler: all of the dead ones in the hospital?]]
* The epilogue is adorable and mellow as [[spoiler: John and Sherlock]] recover for Silent Hill...[[spoiler:...Until Sherlock goes batshit after John confessed his love.]] Just...Damn. MoodWhiplash to the extreme.
* The [[spoiler: drugged]] caffine pills leads to some ParanoiaFuel. Would Mycroft have really [[spoiler: drugged]] Sherlock, or was Moriarty more in control then we knew?
** To elaborate: if Moriarty [[spoiler: could tamper with the supply from Mycroft]], then what else could he have done to Sherlock?
* How broken Sherlock is by the end is truly disturbing when you think about.
