It's understandable as Melissa and Chris are married in real life. But at this point, may as well keep Kara single. William WON'T work (maybe it's just me) and better to keep the theme of women power and all that. It would be huge to have Lex and Brainiac team up, especially for DCAU fans. Not sure if they'll go for it though with all their agendas and all that.
