Mon-El is still in love with Kara, but is it to late to tell her? And what happens if he does? I don't own these characters

Kara has been going through a tough time ever since Mon-el has to be sent away. When he comes back everything is even more confusing for the both of them.

The world as humanity knew it was gone. In its place was a radioactive wasteland, scorched by nuclear furnaces. The third millenium passed unmarked and uncelebrated by those in the safezones. The rich took to the oceans, and to the skies, leaving everyone else behind. Stranded in the isolated "safe zones", with no knowledge of the worlds above their heads. Igor Jonovich changed everything. Nanotechnology, long thought to be impossible, flourished under his genius. Even as the walls of their radioactive cage closed in, humanity pushed back, harnessing Jonovich's creations to explore the radioactive wastelands. To challenge the twisted creatures that lurked in the ashes of their former glory. Humanity thought they, at least, knew this scarred earth. It turns out even that was a lie. Yesterday Jared found a message hidden within Professor Jonovich's greatest work that changed everything.
