Self-help is an excellent start to Sacha Dhawans incarnation of the Master. It serves as a lovely bridge between The Doctor Falls and Spyfall and probably one of the earliest stories in this incarnations timeline as this story is him figuring himself out. Some alone time, some therapy, and some chaos to allow him to reconnect and realise who he is. Dhawan plays the insanity and chaos of this Master perfectly and gets many lovely Master moments, getting a decent array of acting moments in this story. It is a great start to the range and I look forward to hearing much more of this Master!
