When the Flux was approaching the TARDIS, the Thirteenth Doctor unleashed vortex energy from the TARDIS console at it, however the energy appeared to have no effect. (TV: The Halloween Apocalypse) The collision between the energy and the Flux caused the TARDIS and its occupants to fall through time, intially sending them all to the Crimea in 1855 and subsequently sending Yaz to the planet Time and Dan to Liverpool in 2021.
