OK BUT. AU IDEA.
Since at this point it probably COULD be canon-What if the Jerma Dollhouse was a previous Showfall special and Gl!Jerma was a PREVIOUS HERO LIKE RANBOO?? And later since the fans must have voted to keep him around he becomes the puzzler and he’s been trying to secretly get contestants out of Showfall if he can by fake ‘killing’ them on his show- (I know this bit is VERY not canon but it’s an AU for a reason and just a fun concept-) and THAT’S WHY HE LEFT RANBOO A WAY OUT BECAUSE HE HAD BEEN IN THAT POSITION TOO A LONG TIME AGO. Perhaps-maybe the reason he isn’t completely controlled is HIS DEVICE IS BROKEN (possibly earpiece-a reference to the BTS videos that mentioned Jerma’s earpiece was broken-), potentially since that segment in Jerma Dollhouse where one of the demon things yeets him out a window?
