I don't know about you guys, but I have a feeling that Rex's parentage is about to be revealed and the lucky mother is going to be Echo. Now, who will be the daddy is the other issue. It will take some slight tweaking of history, but it could be Clint. They are getting a lot of screen time together, plus, it would explain how Rex was involved in that DNA mess where they thought he was David's dad. I don't even think it has been established who was born first Nat or Rex. Plus, Rex is the age a child of Clint and Echo's would be. She left town 27 years ago. Or it could be Charlie. Remember when Charlie first came to Llanview and Roxie told Rex that Charlie was his dad. He could really be since it will be revealed that Charlie shares a past with Echo. Either way, both tales could be plausible and then finally we will be able to finally put Rex's paternity issue to rest.
