This is a fun two-parter that introduces us to Vicki. With Susan leaving, this is our first companion changeover, but production and the cast do a great job at making this all feel like a realistic part of the universe where this is fluidly happening. No awkwardness, Vicki is introduced and shows off a lot of potential out of the gate. What is less remarkable is the story itself, which I found a pretty simple affair with the whole "fake monster" angle. It works enough, even if I am very glad it wasn't dragged out beyond two episodes.
