I always felt skeptical about Lisa but after watching the update, she absolutely is loving her position as his caretaker/killer. I believe she is in it because she has the victim mentality. She cannot be a victim if he gets better and takes care of himself. That said, he is responsible for himself, as he is an adult. But if you are watching over a drug addict, would you sneak drugs to him all the time if you really wanted him to get better? Same concept with Lisa. Sadly, he is so far gone, it's almost like he is mentally impaired by his food addiction. SHE is the one that is making sure he keeps getting his "fix" and does not get better. I know that if I loved someone, truly cared about them, I would NOT be the cause of their impending death. Also, she voluntarily brings him bad food and extra food and desserts. "Want another helping?" "How does this 1,000 calorie cake look? Looks good? Go ahead and eat it up." etc. He is sad, pathetic, irritating, and not responsible at all but she is straight up evil. SHE KNOWS WHAT SHE IS DOING AND SHE IS GETTING OFF ON IT.
