Phillip Broyles may be a key character in the mythology of Fringe, but not a lot is known about this agent.

Played by Lance Reddick, who has mastered the portrayal of mysterious individuals, Broyles is typically seen at work, conducting business in a no-nonsense, straightforward manner.

But viewers will finally get a glimpse into his personal life this season. Without revealing any major Fringe spoilers, we can confirm that the show has released the following casting notice for "Diane."

African American, in her 40's and attractive. Diane is Broyles (Lance Reddick's) ex-wife. One day guest star. Possibly recurring.

Diane Broyles will be featured in the sixth episode of the second season. As hinted at above, she may stick around beyond that, as well.
