All of them should've been eaten, especially Lindy (Ricky was probably the only one worth saving) I don't think it was explained why the slugs and the dot wants to kill them in alphabetical order but that doesn't matter because they were the true heroes This episode written by Russell T Davies was pretty decent and cool to have a Doctor and Companion-Lite episode, making them try to save someone from afar. I also did like the social commentary of white, rich and privileged kids being ignorant to the world around them Absolutely love Ncuti's performance as The Doctor experiencing racism towards him for the first time, that last scene really elevated the episode for me and gets a half a star, also really like Murray Gold's music during the scene Really like The Doctor and Ruby finally noticing the lady and my crazy theory is that the lady is his granddaughter, Susan, and Ruby is her daughter
