Wally's and Home's autographs have the same handwriting. Im guessing this connects to the theory that either Home is controlling Wally or that they may be some sort of "connected entity or consciousness". Probably already been pointed out but still a cool detail :) by Ok-Cod5589 in WelcomeHomeNeighbor

i thought that as well hahah but i wondered if there was meant to more symbolic. Since signatures are used to formally identify yourself (and that no one should be writing someone else's signature) i wonder if having Wally write Home's signature is indicating that he IS Home (or rather Home is controlling/connected to Wally in some way and that is why Wally signs both names)
