"In the Forest of the Night" is the tenth episode of the eighth series of the British science fiction television programme Doctor Who.
Clara, Danny, and several Coal Hill students on an overnight school trip wake up to find Earth has been covered by large forests.
The Doctor believes Earth is doomed from the solar flare, and offers to take Clara, Danny, and the students away in the TARDIS.
The Doctor hacks into the global cellular network and Maebh reads off a message prepared by the other students to tell everyone on Earth to leave the trees alone, and to request Annabel to come home.
The Doctor responds to Clara's suggestion that he save himself and abandon the Earth with her words to him in "Kill the Moon": "This is my world, too.

She felt that it was "a novel concept that starts off well but unravels fairly quickly",[18] whereas Jamie McLoughlin of Liverpool Echo gave an overwhelmingly positive review, giving it five stars, calling it a "masterclass".
[11] Showrunner Steven Moffat defended the episode, saying it was "beautifully and elegantly written," and added, "I think will grow in stature over the years.
