It might be worth remembering, at this juncture, that no official Amberlynn YouTube video has shown her outside of the house since the "Casting Call" upload of Aug 11, 2018, which (iirc) was still when her videos were lagging behind the actual date.
The only real evidence we have seen of anything resembling walking or going outside since then has been the minute-long Snapchat video of her standing in the doorway on a rainy day. She blew off going to the gym with Becky all this week. She blew off her steps. She lazed around and binged all week...
The Bedbound Saga's demarcation line really seems to be the epic "Hi, I'm Amberlynn" upload of August 16, although her bedbound days preceded that upload by five days. Unless she snaps out of it quick -and she gives no indication that she is likely to do so- that leg and back pain really will be too unbearable for her, and she'll be stuck for real. Housebound, bedbound, doesn't matter... Even the 750 pound fatties on "The Show" manage to get to the kitchen and bathroom sometimes. But that's as far as most of them get.
In a crazy way ('natch) this is what she wanted all along. To be cared for and fed by loyal servants.
Two ways I see it ending... a sudden health emergency, or possible death, puts the Amberlynn Show out of production for good (the spinoff "Becky and Friends" will go the way of AfterMASH, if you'll forgive the esoteric reference). Or a rebellion among Becky, her BFF Eric, and irascible Ricky, and Amberlynn is tossed to the curb.
The next few months will become grim or fascinating (depending on outlook), it seems... Becky actually holds all the cards right now but is too dumb to realize it. Eric is the wildcard. It may be noteworthy that Amberlynn pouts that he doesn't want to play games with her anymore...
Of course, this weird stalemate could also continue for months or even years in its boring way too, but I think something's gonna give sooner rather than later.
