- Henry was sleeping next to a secret room containing the rotting corpse of the psychopath that would eventually try to kill him for two years before the events of the game.
- When you first enter Wish House, you find a note that mentions Alessa, and then you find another note that hints Dahlia is the one that made Walter think Room 302 was his true mother. Since the 21 Sacraments is a ritual from the Order, it's easy to deduce that it's just another way of summoning their "God", and that Walter is just an Unwitting Pawn. If you watch the "21 Sacraments" ending, only his child form seems happy, while older Walter seems depressed. In the end, he didn't get what he wanted, and he probably began The End of the World as We Know It, since what happened in Silent Hill is clearly spreading through the building, and will probably consume all of Ashfield. And he can't stop it, because now HE is the one trapped inside the Room.
- Can you imagine how Henry must have felt when he walked into his living room and saw a ghost coming in through his wall?
- How about just waking up to that ghost, period? It's rarer than in the living room, but that haunting can also happen in the bedroom and the laundry room.
- The realization that Walter's Otherworld, unlike previously encountered ones, wasn't born from a troubled person's negative feelings, but intentionally created. This world of violence, insanity, and Everything Trying to Kill You? It's the world as Walter wants it to be, the one where he feels like he can most be himself and where everything makes sense to him. It's his idea of Heaven.
- Supposedly "trapped" in his apartment, Henry never tried breaking through the room's windows, which despite being locked, could be smashed through with, say, a chair.
- Mr Dull Surprise doesn't give the impression of ever having a rebellious bone in his body. Thinking of using bedsheet-ropes or drain-pipe climbing frames to sneak out of high windows doesn't fit his MO.
- Given that the room is suggested to be in another dimension, smashing the window wouldn't do any good.
