On the March 18, 2015 episode of "The Bold and the Beautiful", Maya's (Karla Mosley) secret was revealed by her sister Nicole (Reign Edwards). Below I discuss my thoughts on this development so far, and link to some press articles on the topic.
Maya was born Myron, and is transgendered. Karla Mosley, who plays the part, is cisgendered. While the story is surprising, the main reason I find it to be is that it was established on camera that Maya had a child. This daughter was put up for adoption as Maya was in prison, but sadly died before Maya was released. Due to the character's backstory, I hope Maya will be intersex, or else they have a lot of explaining to do in regards to her daughter. Maya wasn't married, and we met the baby's father, usually young single people aren't allowed to adopt. (If the baby wasn't an issue in her backstory, I'd have no problem with Maya being born 100% physically male instead of intersex.)
I hope regardless of what happens the story is respectful of transgendered people and isn't written for comedy. I also hope they actually bring in transgender performers in more than walk-on roles. If they make it that the other Forresters use Maya's situation to ruin Rick personally or professionally, I'll be a bit annoyed. Rick's soon-to-be ex-wife, Caroline, is the daughter of a lesbian couple, so if they have her attack Maya being transgender I'll call foul. There are "low blows" and then there is patently offensive. What amazes me with this is how for so long B&B got flack for not having any regular characters in the fashion, who weren't straight. Now with this, they have jumped way ahead. Historically soaps are known for social issues, and B&B now has remembered those roots.
Here is the coverage from "The Wrap" that includes a video with Brad Bell the head writer and executive producer and Karla. This is what "USA Today" has to say, and "US Magazine"'s coverage.
