So, they're REEEEEAL light on the details for Jenkins. But there are hints here and there, the biggest of which would be when he bonds with Stone over having difficult dads.

I love going back to rewatch the scene with Jenkins and Dulaque in the dragon ep with the knowledge of who they are to each other. I mean, if nothing else, just the look on his face in the icon on this comment . . .

Ugh. John Larroquette, how are you so good?
