Since multiple actors from Buffy the Vampire Slayer and Angel came forward to support Charisma Carpenter's allegations of on-set abuse from showrunner Joss Whedon, other former Whedon co-workers and actors are calling the writer out on his past behavior.

The latest is Firefly writer, Jose Molina, who took to Twitter on Friday night to call out what he referred to as "casually cruel" behavior by Whedon.

Ray Fisher started the dialogue about Whedon's alleged abusive behavior when Fisher spoke out about his treatment during the filming of Justice League, which Whedon took over as the director on after the initial director, Zack Snyder, left the film following the tragic death of his daughter. Former Buffy and Angel star, Charisma Carpenter, then started a whole new line of discourse when she posted of her own alleged abusive experiences with Whedon while saying that she stood with Fisher.

Now, Buffy and Angel stars and writers are joining Carpenter to stand with her, as well. Buffy star, Amber Benson, wrote on Twitter, "Buffy was a toxic environment and it starts at the top. @AllCharisma is speaking truth and I support her 100%. There was a lot of damage done during that time and many of us are still processing it twenty plus years later. #IStandWithRayFisher #IStandWithCharismaCarpenter"

Molina then replied to Benson on Twitter, adding his own take:

"Casually cruel" is a perfect way of describing Joss. He thought being mean was funny. Making female writers cry during a notes session was especially hysterical. He actually liked to boast about the time he made one writer cry twice in one meeting. #IStandWithCharismaCarpenter

Molina was a writer on the sole season that Firefly was on the air, and served as executive story editor on the series. He wrote the ninth episode of the series, "Ariel," as well as the eleventh episode, "Trash." Molina has since been a writer and co-executive producer on a number of shows, including Without a Trace, Castle, Grimm, The Vampire Diaries, Sleepy Hollow and Agent Carter.

He follows former Buffy writer (and Whedon's successor as showrunner on the series), Marti Noxon, as someone in the writing room with Whedon coming forward with support of the allegations of abusive behavior by the writer.
