This is an age old post - Logan Grove's casting was leaked a year or so ago. He appeared in this week's episode, "Image". The two sources for it were quickly taken down: Grove's twitter, and an article on his agent's website.

As for the female member, Zatanna's joined. Wonder Girl (both versions) was unavailable for use in season one, but no word on whether she will appear in season two.
