Looks like Ringer and Supernatural are playing switcheroo.
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 Martin.
Expect to see Jason pop up on Supernatural in episode 12, set to air sometime in mid-January. And expect to see Juliet attempt to seduce Mr. Carpenter sometime very, very soon.
