Maybe but I read that he is scheduled to be filming a movie next year at the same time Homeland will be filming so I think he is gone.

I can see that.

Finale should have been 2 hours long - you're right. They had to wrap too many things up so had to be tidy and didn't give endings they deserved. That being said I thought they did a good job in only one hour.

The light is symbolic of something but I think the purpose of her putting his vitals on her finger is that she was going to put him out of his misery. They just didn't want to actually show her doing it. He is gone.
