10 Doctor Who Fan Theories That Became Fact

Though it ultimately didn’t amount to anything, the Thasmin fan ship was so popular that it caught the attention of the Doctor Who showrunners.

A potential romance between Yaz and the Thirteenth Doctor was speculated about from their first series together, despite the show having no intention of even hinting at the idea, let alone developing it.

That is, at least, initially.

Fast-forward to the latter stages of Thirteen’s tenure and the 2022 New Year special Eve of the Daleks, and Yaz would reveal she has romantic feelings for the Doctor, something that had started to be hinted at during Series 13 in 2021.

This revelation in Eve of the Daleks wasn’t part of some long-term plan from the showrunners however. As confirmed by executive producer Matt Strevens, it actually only originated after the Thasmin fan theory had been brought to his attention by Jodie Whittaker herself. Strevens said:

"I didn't know what Thasmin was. Jodie said after the first season, 'Oh there's speculation out there', but we hadn't really thought about it. [Thasmin] was something that [showrunner Chris Chibnall] wanted to bring in and sort of play with.”

For his part, Chibnall would later acknowledge regrets about Thasmin never developing into a full-on romance or even a kiss, saying that, while he intended for it to be an unrequited love story, he wasn’t sure whether that was the right decision.

Thasmin shippers, what say you!
