If you're watching Season 6 just skip this episode entirely. It's completely useless to plot of the Season 6. The episode is a cheap thrown together episode directed by the guy who did the Supergirl movie from the 80s. The plot, the acting, the logic, really just everything is thrown out the window to make a useless episode that only exists to fill a void. Not even the title makes any sense! I would go out on a limb and say that this might be the worst episode of the entire show.
