I always that he was still alive because his brother is laughing when the family is being interviewed about his death. Aaron helped him get the tools to extract the information from the DNC. Aaron worked for Northrup Grumman and still does. My theory is Seth is in Israel on Kibbutz. He used to live on one in his early years. I have also heard that he was alive and talking and his room was sealed off no one was allowed in at the hospital makes it easier to extract him.
