Dorothea Ames became headteacher at Coal Hill Academy in November 2016, replacing Frank Armitage, who had recently died.
Ames suggested that she worked with the mysterious Governors. When Miss Quill entered her office, she asked for her help with the invasion of killer petals. In return, Ames offered to removed the arn, giving Quill her free will back. (TV: Co-Owner of a Lonely Heart) She took Qill, Charlie Smith, and Matteusz Andrzejewski to their house in order for her to force Charle to use the Cabinet of Souls to destroy the killer petals. She placed a gun on Matteusz and was delighted that he eventually armed the weapon. As part of this she accidentally turned her back on Matteusz who knocked her out. After the petals were killed, she said to Quill the the Governors had predicted the outcome and that the offer of removing the arn still stood. (TV: Brave-ish Heart)
