I like the Kyle/Carol relationship. Yes its because I'm probably the biggest Kyle Rayner fan and I feel he deserves to be happy. I think that the relationship that Geoff built for Hal and Carol was never meant to go anywhere. Hal can't grow up. He's not meant to be in a relationship. At least not a romantic one. His path, his destiny was always to be the leader of the GL Corps. That is why the dynamic of his and Carlo's relationship would never work. He was more about being a hero to everyone else than being a companion to anyone.
The Flash and Patty Spivot though. That bugs me. I don't like that. Its supposed to be Flash and Iris. Not some chick he works with just because she is on the same intellectual level as him. That won't work. I truly believe that they will be killing her off. It will be something that is considered his greatest failure. Almost on the same level as Kyle and Alex.
