HBO’s Watchmen sequel series is set to debut this fall, and yet so much of the plot is still unknown. One such mystery is the name of Regina King’s superhero persona but now, thanks to an eagle-eyed fan, it finally may have been revealed.

Recently, hbo.watchmen noticed that HBO posted an image of King in her costume on their site. When you check the URL of the image, it includes the phrase “Sister Night.” Based on this information, it seems clear that this is the name of the star’s character.

It has been rumored for some time that this would be the character’s alias, but it is good to have found some confirmation. Hopefully, as we draw closer to the series debut further details will be revealed.
