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.

On the two year anniversary of her father's death, a creature called the Lan Kin came through the rift and took the form of people's dead loved ones. The Lan Kin, in the form of Jasper Adeola, tried to entice Tanya into embracing him and thus allowing the Lan Kin to feed on her grief. She knew that this was not her father, and poisoned the Lan Kin with the anger she felt when her father died. When Miss Quill drove a double decker bus into the trunk of the Lan Kin, it knocked the doppelgänger of Tanya's father out of the window, and in weakened state, the Lan Kin retreated back into the rift. Tanya later reminisced about her father with her mother. (TV: Nightvisiting)
