Looks like Ringer and Supernatural are playing switcheroo.
On the heels of Supernatural's Misha Collins signing on to guest on Ringer, Jason Dohring is booked to appear on Supernatural in an upcoming episode, according to TV Line.
Jason will be playing Chronos, the God of Time, which is apt since on Ringer, his super-nice teacher character, Mr. Carpenter, has basically become a god to Juliet...
