Of all the ways I had thought that Simon might return, his arrival in "Tipping Point" as the leader of the extraction team working for Strong never crossed my mind.
In my version of events, James was working for Simon and that would be the big reveal at the end of the episode: Simon living a life of luxury in Latin America and James bringing Michael to meet him. I've never been so happy to be wrong about a story plot in my whole life.
Actually, there were a lot of surprises that made me really satisfied. As wrong as it sounds, the top of that list was Michael winning the fight against Simon and assuring that Simon wouldn't hurt anyone again.
