Say, have you been enjoying the fact that because Clara and Danny now work in Coal Hill School that a lot of these episodes have featured children in some form or another? Because if you haven't, you really aren't going to like In the Forest of the Night. This week, rather than just one or two kids we have a whole class of them, as Clara and Danny navigate a class through a huge forest that has inexplicably grown all over the world overnight. Even the Doctor doesn't seem to have an answer for why this has happened. As humanity attempts to rid the world of these mysterious flame-proof trees, the Doctor seeks help from a young girl who seems to be seeing more than those around give her credit for.
