Season 1, Episode 5 – “Brave-ish Heart”
Battling through the Shadow Kin realm, April knows that there is no going back: she has to defeat Corakinus. On Earth, the invasion of the petals is rapidly snowballing. Confronted with the threat of the planet’s extinction, new headmistress Dorothea attempts to force Charlie into making a transformational decision. But Miss Quill has other ideas for him. As Charlie, Matteusz and Tanya try to stop the petals from annihilating the human race, April must fight the terrifying force of Corakinus, light years away from home.
The sixth formers of Coal Hill School all have their own secrets and wants. They have to deal with the stresses of everyday life, including friends, parents, school work, sex, and sorrow, and also the horrors that come from time travel. The Doctor and his time-travelling have made the walls of space and time stretch thin, and monsters beyond imagining are planning to break through and wreak havoc upon the Earth.
