The show will not be the same without Charlie. He really is the heart of the show. If his death was not planned since the beginning, I see no reason to go through with it. There are plenty of places to go with him now that he's not a junkie. His relationship with Claire and Aaron was never fully explained. Maybe he could come back and finally he and Claire would get together. If they're getting off the island, I would love to see what their life would be like together as a family. The show will suffer without Charlie. Bring him back.
