Who Is Supernova?

Supernova's identity has been one of the biggest mysteries floating around in comics for the past few months. I had thought I had figured it out several months ago when Booster Gold died, but with more recent events, I'm just not sure anymore. Up until issue 31 of 52 I was sure that he was the new Starman we saw at the back of Infinite Crisis and now in JSA. Back in the 90's Starman series, Jack Knight meets several Starmen from different times, including one from both the 31st century and the early 21st. This Starman, Tom "Starboy" Kallor of The Legion of Super-Heroes had grown up following in the footsteps of the Starman lineage and had come back in time at the Shade's urging. When he arrived in this time he took the name Danny Blaine, and adopted the Starman costume we first saw in Kingdom Come. Supernova's costume design, while based off an old Superman costume, see Worlds Finest #178, has a large star on the front, also all of his powers are similar to the powers Starboy had, with maybe a few tweaks since he was older and more experienced. Now we see the Kingdom Come costume being worn by the new Starman in Justice Society of America. But this Starman is crazy, makes no mention of any time in Metropolis, and operates out of an asylum in Opal City. Which is a nice touch, since the original Starman, Ted Knight, suffered several mental breakdowns of his own over the guilt of helping to design America's first atom bomb.

In issue 31 of 52 Ralph Dibney mentions that all of Supernova's powers can be explained by one device. One DEVICE? Tom Kallor's, or Danny Blaine if you will, powers were a natural part of him. Also Ralph is certainly familiar with whoever is under the mask, more then just a passing aquientence too, it would seem. Dibny and his wife, Sue, were also in the 90's Starman series, and had actually settled in Opal City until the events of Identity Crisis. Could it be now that while the Starman connection was accurate, I had the wrong one? It was promised to us long ago that yes, we would see Jack Knight in 52, and he has yet to appear. Jack had also talked about how, save his father, Superman was the one hero who inspired him more then any other. Could it be that Jack, wearing one of his father's cosmic rods, has taken upon himself to protect Metropolis while Superman is gone? I just don't know any more.
