I think those female directors were already planned for season 11 because you don’t cast directors last minute. I think Gillian didn’t know but it doesn’t matter because it’s still only 4 female directors all together, so nothing to be proud of. I think it has nothing do to with Gillian’s smokescreen-fight for gender equality in txf.
I just hope they didn’t hire them because they’re women but because they’re talented, understand and love the show and its characters.
