Honestly, wouldn’t it be cool if we got him to publish even that one last episode of TBBBTEBB? I’m sure he has it written somewhere, that’s why he knows the fourth episode is the last…
Even though his episode instagram is inactive, he most likely has a non-episode instagram that’s currently in use. It’s kind of a long shot but if we found his current instagram we could figure out what he’s up to. Probably not wasting his time on episode anymore.
