Something occurred to me while I was watching tonight's stream, does Jim have multiple sclerosis? His symptoms sound similar enough, and new research came out that indicates MS is caused by Mono, wherein people affected by the disease have immune cells that will confuse an EBV protein called EBNA1 for a myelin protein called CRYAB and continue attacking the misidentified myelin proteins. It'd explain why Jim's eyeballs are rolling around in his sockets and why his hands don't work properly, it would also explain his bone breakage since MS is associated with low bone density as well.
