User blog comment:Dtuck010/Theory why Nightwing, Miss Martian and Superboy didn't want to join the League/@comment-75.1.177.162-20120503205322/@comment-4454131-20120503210334

I figure if he ever joins he'd split his time between the team and the league (assuming that's doable). I'm happy with where he is and even though he isn't actually a leaguer he still has access to all their stuff and seems like he can go to the watchtower and help out anytime he wants. Then there's that alien plannet keeping tabs on new league members... noot exactly a good time to join.
