In today's Comics Continuum preview of this week's new episode, Child's Play, there were a couple of season two tidbits thrown in at the end. The first one was the confirmation of Andy Milder returning to voice Lightning Lad for the season. The second said simply:

Look for Chameleon Boy to appear in Season 2.

This will be great news for a large number of Legion fans. Of course we don't know yet if it is a one episode appearance, a recurring appearance like the upcoming addition of Cosmic Boy to the team, or if he'll be a member of a refocused team.
