Welcome home theory I understand if you don’t agree with my theory 
Home has said that Frank is an object. Frank often helped his friends with their issues and has to deal with a lot of their problems, which is something an object would do. It’s only purpose is to be there when everyone needs it or need to take care of the problems 
I don’t know if Frank on the plate is helpful, but I think this can mean something and some old things from clown has become canon so maybe this can become canned as well
How his neighbor treat him
Barnaby seems to harass make fun of and prank frank a lot.Frank seems to be fed up with it. But even how hard he tries, he can’t stop Barnaby harassment and Barnaby doesn’t seem to stop either even when Barnaby is helping Frank find him a new chair he’s still being kind of an asshole and also when Frank is having his meltdown. He starts getting scared that Barnaby is in his house and maybe he pulled a prank or he went in the shed. He called an inconsiderate dog, just shows how Frank hate him
Barnaby thinks this is some kind of joke and probably thinks he’s free entertainment 
Sally seems to not like Frank either they fight often and in the sweet lavender video we got Frank says it’s always with these prince rolls Sally also seems to push Frank a lot. I don’t know what she could think about him. Maybe a person she needs onset or a prince for the princess
Howdy is not a nice guy eater. He’s like Barnaby, but less jokey and more hateful he bad mouths frank a lot
Julie lean on Frank a lot when she needs something or is dealing with something he comes with her needs like the flower when she’s dealing with the flower, she doesn’t want Frank to come with her but Frank and see it and knows that she has to get rid of it before anyone else can see it and knows he’s the only one that can help her so he gets rid of it. it (I’m gonna have mixed opinions on this, but) I think Julie eater has a crush on Frank or just happy when she’s with Frank does not feel the same way however, like in the sweet lavender, .he imagined Eddie, not her and she seems to be either sad or angry
Poppy deals with a lot of issues Frank is there when she needs someone to talk or just hang out with .after Frank visit Julie when she got sick he’s concerned for her for all the locks she has around her house and doesn’t know when she’ll probably ever calm down and he seems to be one of her only friends that knows about the bog in her home also, I think Frank grew it. for her or she grew it herself because Frank is the only neighbor that has a garden
Eddie seems to not remember his past with Frank. It seems like they had a relationship going on but Eddie forgot when he moved in. Frank seems to be frustrated with him but trying to stay positive as possible. Also, sad thought, but what if Eddie had numerous times were in the neighborhood not remembering Frank at all had broken his heart a couple times and Frank seems to be either fed up or upset with it then, maybe half of his anger comes from this Frank loves him, of course, but why does Eddie not remember?
Home has grown a liking to Frank. He had taught him Morse code how to speak to others. It seems like home enjoys Frank. And he’s the only one to have a different expression, unlike Julie either this can be the bug or maybe home know something else?
Wally is questionable he seems like Wally likes Frank. He wants to learn things from Frank. He wanted to learn morse code to speak to home. He wanted to learn about crayons and colors in the just so Frank is Wally‘s teacher, but this update it seems like Wally does not want him to leave or wants to lead Frank on some other path unlike the others
A little detail, I realize that aftermath of harming where it shows Wally holding Frank back from going to Eddie Wally‘s eyes have blue and red. It’s kinda hard to see for Frank’s eyes since they’re kind of small, but it seems like one of Frank’s eyes is blue and red like Wally I saw someone said that Frank’s eyes were red, but I don’t think that’s true. Either this can mean Frank and Wally are connecting somehow or they have cameras in their eyes. and another thing I saw I don’t know, if I’m right, but Wally‘s blue eye is on his left and Frank’s blue eye is on his right eye 
We all know that Frank is a grump. It seems like Frank’s grumpy personality mostly comes from the neighbors treating him pretty badly. He seems to really love his friends, but at the same time they were lean on him too much and he seems to drive him crazy plus all the stuff going on he can never find time for himself because of how everyone is always needing him or harassing him plus, he’s already dealing with his own stuff. He seems really tired in this update if you see his eyebags and he lost his journal. He needs to find his journal to get his memories back. He knows something isn’t right in this town.
Also, whatever Frank found in that envelope could make him snap or make him help everyone get out of here
And what I mean by snap I feel like Frank might kill someone he already did it before
Frank seems to have a really liking for this butterflies obviously Frank loves butterflies. He loves all kinds of insects, but he seems to really lean on butterflies I know that sounds crazy but what if Frank had some kind of connection to it maybe he came here because of this butterfly he’s looking for he’s journal but what is it actually looking for something else Is it for the butterfly?
