It makes sense that a Doctor Who spin off would eventually travel back in time but I didn’t expect it to happen in series one. Through a delicious sci-fi twist we see a 13-year-old Sarah-Jane’s friend become twisted by trauma and become a pitiful, yet abusive and powerful villain. The fact that Angela, at a glance, looks so similar to Sarah-Jane is spooky! The return of the Graske is unexpected and cute - but it’s the faceless Trickster that imprints itself on the mind's eye of a child.
