Something hidden (some white snow on Jim's hair) lies in Josh's new Instagram post via his Jim Dun account. Fans speculate that he flew from LA to Ohio to visit his bandmate Tyler Joseph on his birthday. A Google search showed that weather in LA on Dec. 1 is lots of sunshine. Not a piece of snow.
(The background here is that, ever since quarantine, Josh is living in LA while Tyler stays in Ohio, which is usually the case here because Tyler doesn't own a house in LA.)
I think Josh has really learned how to tell a story without talking about the main subject. Maybe he learned it from Tyler.
