Recced because: Most people would just be grateful if the Doctor saved their lives. Luke worries about it, in a wonderful display of existential angst and dawning apprehension. The story is simply a beautiful character study in which Luke gradually realises that his rescue could be a very bad thing, compares his rescue to the many deaths that the Doctor didn't prevent, and tries to work out how he can still be alive without damaging the timeline.
