In Episode 37 of CEREBRO, Connor and Marvel writer Steve Orlando get bad to the bone with the Morlock Sarah Rushman*, better known as Marrow! A breakout character of the late 90s, the rebellious and grisly Marrow's rising star quickly flamed out, but she's endured as a fan favorite.
The CEREBRO character file on Marrow begins at 26:58.
(Content Advisory: Sarah's story includes genocide, child abuse, sexual violence, torture, a non-consensual pregnancy termination, brainwashing, and general body horror.)
* NOTE: At the time this episode was recorded and published, Marrow's civilian surname "Rushman" had only been presented as an alias. As it's now being presented as her legal surname, and this episode had pretty bad SEO as just "Sarah", I've elected to rename it!
