No, that was a rumor that’s never been proven, in fact that was debunked by the developers themselves, SH4 was in development during SH3 and SH4 does have major connections to the other games.

1. Walter Sullivan was first referenced in a newspaper scrap in Silent Hill 2 as having killed himself shortly after killing twins Billy and Miriam Locane. These two victims also appear in the form of the “twin victim” creature Henry encounters.
2. The investigative journalist Joseph Schreiber, was first referenced in Silent Hill 3 with a magazine article he has written condemning the Hope House orphanage run by The Order which the game’s protagonist, Heather, can discover at Brookhaven Hospital.
3. Frank Sunderland is the father of James Sunderland from SH2. He is said to have disappeared in Silent Hill together with his wife several years ago.
4. Walter Sullivan’s gravesite is visible in the graveyard later on in SH2.
5. The Robbie The Rabbit doll can be seen sitting on Eileen’s the bed. Robbie has appeared in SH3, SH: The Arcade and SH: Homecoming.
6. The Halo of the Sun, first appearing in SH3, is seen during the loading screen and are the holes which Henry uses to travels between his apartment and Walter’s world.

I’m not trying to take this so seriously or anything, but he claims it’s just a joke but with no “lol” or smiling face or anything to let others know that he’s just joking, no one can hear the tone in someone’s voice through simple text. But then he still tries to make it seem it’s possible because we know very little about him?

Your assertion of Henry as devoid of emotion is also unviable. He exhibits emotions many times throughout the game, i.e. Cynthia’s death, when he tries to intervene on Richard Braintree’s electrouction, his recurring affection for Eileen and the angst he shows when he fails to prevent Older Walter from kidnapping young Walter (proclaiming “damn it” at the Toluca Lake”)

Furthermore, the peephole he uses to spy on Eileen was made by the previous tenant Joseph Schreiber (refer to silent hill wiki) whom we can infer as being a pervert from the memos (mike’s diary) dictating him giving “rare porn magazines”

“The last few months, Joseph, the guy next door to me who gave me that rare
porn magazine, looks like he’s been working super hard.
He said if he found another rare one, he’d give it to me but he hasn’t shown
his face around much lately.

He said he was a journalist and he is always investigating stuff.
But I think something strange is going on with him. He’s been shut in his
apartment and I can hear all these weird noises coming from there.

Henry is anything but a pervert. He doesn’t even respond when Cynthia offers to perform the “special favour” for him if he helps her get out of the subway world, accentuating his shyness.

Nonetheless nice analysis of the gameplay.
The use of graphics, particularly in the cut scenes and in the 1st person view were impressive for its time. I also like how Konami inverted the concept of the room as being the safest place in the world for a person. Overall I though the game was one of the best. It combines many great features including a plot which is deeply interwoven with the silent hill lore, good gameplay, graphics and one tough antagonist.

I give your article a 9/10!
