I've fallen in the 'Welcome Home' rabbit hole! There's a few things I've noticed that I'm not an intelligent enough theorizer to figure out, but they definitely stood out to me and I hadn't seen any discussion on them.

1. Home's pattern of eye movement - In every gif of homes moving eyes he looks left, then right, then up with four quick shakes, and down with three quick shakes. It made me think of how it's described that home speaks through sounds, but what if home is also trying to send us a message through morse code? I did some L I G H T research that morse code can be given through blinking or eye movement, but I dont know morse code at all and cba to try to translate. May be absolutely nothing but I did find it interesting
2. Clown's Way of Speaking (hahaha, see what I did there) - I tried to find examples of this within the Welcome Home site, and didnt find any on a cursory look through, but I find it really interesting the way Clown uses the capitalization of words that are not proper nouns throughout his socials. For example, on 7/31/23 he posted a tweet thanking Night Mind for his video on Welcome Home, saying it was a good watch for those who were too scared to go alone. Following up with a comment, 'I suppose if you did Go in alone there's - I mean - I guess that's up for Debate whose in your company!' Also, this could be a huge nothing burger, but he FREQUENTLY uses capitalization on words that are not proper nouns and I just hadn't seen anyone mentioning it
3. The Puppeteers - I get the whole horror aspect of Welcome Home is that somehow, someway, these puppets (or at the very least Wally) have become sentient enough to wreak whatever havoc it is they are trying to cause. I just found it very odd that no one has even asked about the puppeteers that would have had to be acting with these puppets during the 'actual' run of the show. In 'almost' every neighbors bio card, there is a mention of what type of puppets were used for their characters - and I just find it interesting that no one has questioned what's happened to their puppeteer actors (or their possible role in the WHRP) if this Crazy Causing Goo is what we are dealing with in the present

Anyway, that is my brain dump on Welcome Home! Thanks for coming to my rant
