(It should help that she and Brennan ended on a good note last time.)
I’m sure Dr. Brennan will not be super pleased about having to work with the world’s most foremost expert on forensic anthropology again, although it is clear that Mayer should contribute to the case.
In fact, the first time she showed up we learned she was the person who basically innovated the computer platform that Angela has been using since she joined the Jeffersonian, so she’s clearly a woman of value.
Deadline reported the casting, although the episode doesn’t even have a name yet, much less a premiere date, so it’s very difficult to tell exactly what Dr. Mayer will be doing back in the plot.
