After he was legally declared dead more of his personality was shown. The man was a pack rat collector who had the worst luck with women, already having two ex-wives to prove that point. The latter being a trait that would lead him to his partner/lover the woman that would later be referred to as Lady Chronos. For reasons that were never entirely clear Clinton (one version of him at least) returned from his apparent grave to led Ryan Choi to become the fourth Atom when Ray Palmer went missing. To embarrass the legacy of his foe but in a possibly future it is implied that he undermined Lady Chronos to ensure that she was stopped by messing with Ryans' life.
Current Status: Given how often his story changes it's hard to say. He faded away until Lady Chronos came into the picture. In a future where she rules the entire timeline Clinton is a living statue next to her throne. She comments that he cheated death many times "eventually he had to learn that time doesn't heal all wounds." Of course this claim is at odds with her later statement that she "collared" him herself.
