I don't want to sound morbid, but if Archie's has technically passed away, then why isn't he decaying? His skin etc looks healthy, and surely he would smell if he wasn't alive?
Holly has previously said they (the staff) have the air conditioning on in Archie’s room and that “it’s freezing” and my first though was that they’ve done that to slow down the natural decaying process.
Ive seen video clips where there is a flash of his arm or leg but I haven’t seen any that show his face for quite some time whereas before it was common for her to do that. I imagine there’s a very good reason why she doesn’t show him fully in the videos anymore….
