In Justice League Dark this week, Black Orchid (as well as Frankenstein and Amethyst) is lost among the shifting and bizarre rooms of the House of Mystery, and she stumbles into what appears to be Constantine's office, where he has photos of and notes about various super people. The most interesting bit apparently had to do with Wonder Woman's friend on the apache reservation, mentioned a few issues back in JL. A note attached to a picture of Black Adam and Sivana says (along with some other stuff about Shazam) "The Circle of Wizards: Shazam, the Apache, who else. Need to check out Cold Dog Apache Reservation: Arizona. Find the new kid." So, I guess the old woman we saw in JL when Wonder Woman's Apache friend was mentioned is a member of the Circle of Wizards, and the young woman is her counterpart of Billy Batson?
Also on the wall is a note wondering this about the JL: "--Does Trevor know who they are? --Wonder Woman and Steve Trevor. Possibility to exploit this." Interesting that Constantine (assuming that these are his notes) was thinking along the same lines as Graves.
Steve Trevor's in the issue too, ordering ARGUS agents around, trying to help get the missing Tim Hunter and Zatanna back, and getting a hard time from Constantine, who asks if he got ousted from the "the big kids club" because Wonder Woman
caught him wearing her knickers again.
There's also a little tease for Trinity Wars at the end. The Phantom Stranger tells Constantine that these will be a war among the three (presumably the Stranger, Pandora and the Question) and Constantine will have to decide whose side he is on. Meanwhile, Pandora is watching.
