I would actually like to see Jefferson featured as the final villain of OUAT, the entire season dedicated to him. Flashbacks could include what Sebastian Stan was doing all this time, and what he was going through while our heroes while battling Pan and Wicked, and even what happened to his now deceased wife.
His ultimate motive would obviously be to be reunited with his daughter, Grace, doing whatever it takes to accomplish that, driven by his now out-of-control insanity. And just to add a branch to the family tree, Grace and Henry could get together.
I don’t know about you, but I would love for this to happen!
