EW has noticed a new billboard that has popped up in LA. The mysterious diagram was last seen being written by Director Phil Coulson in last season’s finale of Marvel’s Agents of S.H.I.E.L.D. The diagram seems to be a result of the elixir that brought back Coulson from death as it was also seen being drawn by John Garrett following his exposure to it.
Marvel’s Agents of S.H.I.E.L.D. returns September 23 at 9/8c on ABC.
Update: The billboard has been updated with Director Coulson and the show’s season premiere date and new timeslot.
