An excellent character piece for Charlie Smith. The diary format allows us to dig deep into Charlie's inner thoughts and feelings, including how he feels like an outsider on Earth, and his misunderstandings of things like superheroes and animated gifs. There's some nice comedy to be found in his description of how rude Miss Quill is to the other students, including telling their parents they should suffocate their kids and try again.
Most revealing is how it describes how stark the transition is for Charlie, going from a world where everybody knows who he is as a prince to one where he's just another student studying at Coal Hill Academy, and people barely give him any attention. It really shows how alien the planet Earth is for him in comparison to when he was a child on Rhodia. Although his childhood on Rhodia isn't much better either, given how his parents barely seem to care about him, from how Charlie speaks about them.
A major focus of this audio is the romance between Charlie and Matteusz, which gets fleshed out more than it did on TV. It makes sense how Charlie discloses that he feels a strong connection to Matteusz because of how he is an outsider like him, because of how Matteusz is originally from Poland trying to fit into an English school. These are two people who feel an instant connection, because of how they feel as though they don't belong.
Surprisingly, Secret Diary Of A Rhodian Prince closes with a continuation of the Class cliffhanger. I was not expecting to hear Cyril Nri reprise his role as the Chair of the Governors, who gets ahold of Charlie's diary, and reveals how the Governors are trying to help separate April from Corakinus's body and return her to her human body. It makes me hope we get some Class audios at some point set completely after Series 1, with the Weeping Angels.
