Three years later, she started sixth form. Tanya struggled making friends at Coal Hill Academy, due to being younger than everyone else. The one student who offered friendship to Tanya initially was April MacLean, though Tanya wasn't entirely happy with being friends with the school's social outcast. She regularly helped Ram Singh with his homework, and in return, he would pay money into her gaming account. During one of their video calls, Tanya was attacked by a Shadow Kin. She managed to defeat it by removing all the shadows from the room. This knowledge would later help her and her friends, along with the Twelfth Doctor and Miss Quill, temporarily defeat Corakinus and the Shadow Kin at the Autumn Prom. (TV: For Tonight We Might Die)
Tanya continued to do video calls with Ram after the prom. She told him about her dad's death and how she coped with it in order to show him that she understood what he was going through after the death of his girlfriend, Rachel Chapman. She helped Ram investigate a skin-peeling dragon at Coal Hill. She later witnessed Mr Armitage being skinned alive by the dragon while trying to protect April, Charlie, and Tanya herself.

On the two year anniversary of Jasper's death, a creature called the Lankin came through the rift and took the form of people's dead loved ones. The Lankin, in the form of Jasper, tried to entice Tanya into embracing him and thus allowing the Lankin to feed on her grief. She knew that this was not her father, and poisoned the Lankin with the anger she felt when Jasper died.

She started to become paranoid, especially when Paul started hanging out with her friends. She later apologised to Paul about it.

When Tanya saw Amira seemingly calling for help from a window of an old stone house in Shoreditch, she first called the police.

Tanya managed to persuade all Coal Hill defenders to go and check what was wrong with the house. During one of their visits, the female bone spider living in the house managed to separate Tanya from the others and trap her in the house. There she became friends with Amira, another prisoner of the bone spider. Neither Tanya nor Amira could see who is keeping them in the house. While the spider was distracted by the demolition crew, the girls had a chance of escaping. Instead Tanya insisted on getting to the bottom of this business. Thus, she confronted the bone spider and, though initially scared, soon realised she did not mean to harm anyone. When Miss Quill, Amira and Alan Turnpike captured the spider in her own web, Tanya freed her despite Miss Quill's protestations. Only then could the communication between the spider and the humanoids be established.

Together with Alan she found the baby spider in Parsons family vault and brought her back to the house. She helped Amira report smugglers to the police. (PROSE: The Stone House)
