i think it because he carries too much stuff in his shoulders. He is clone made with Dna of his mentor and his Arch-Rival. He cannot age outside but he can age inside. He probably knows that he is only sidekick that never could be on his mentor´s level in natural full strength. Plus He knows that he isnt powerfull enough to be beat some people like The Match. Also there is he break up with Miss Martian due probably Miss Martian start to use her as she wants and dont care who she hurts, and he is always to watch his ex-girlfriend in another man´s arm, that he thinks that he is jerk. If Supergirl would appear on this show, that would be too much for him.
