The only evidence I can think of for Serge/Kid pairing is Leena's fortune reading of "You will not have a boyfriend for a long time." (quote isn't exact)
Now this could just mean the future of THAT Leena, who lives in a world where Serge is dead, OR the fortune teller is looking into her final fate, after TD is beaten, and sees that she is seperated from Serge. But that's really stretching it considering, the whole Komodo Scale thing.
