I wouldn't be so sure, Christina. This is sci-fi and he's working for a government agency. He could very well be undercover/on a mission to another planet/hurt in an accident and now has superpowers, etc. The family could have merely been told he died. After laying out that line about how he knows so much information about Superman, I doubt that's the last we'll see of him. Dean Cain is a hotter commodity than Helen Slater, and certainly a bigger tv audience draw (he is constantly showing up on Fox News), and Supergirl needs all the ratings it can get. He only has a supporting role on Hit the Floor, which was taping around the same time as these Supergirl episodes, which could easily be worked around since they both shoot in LA. Hit the Floor filming is done now, so his schedule would be open again.
