Part 2 of the Secrets webisodes compilation is well-worth watching, too.
In the first section, Marientte tells her diary how she feels about the city of Paris, her thoughts about fashion, design & art, and how she feels about Gabriel Agreste.
In the second section, we watch a video made by Alya welcoming visitors to the Ladyblog, and explaining her purpose and vision in creating the blog.
Then in the last two sections we get to hear Adrien's thoughts in his own words - how he feels about his life, his father, his career in modeling, and various other people in his life. (He calls his bodyguard/chauffeur "the gorilla", so apparently we never ARE going to learn his real name - not that it matters much.)
In the very final section Adrien is sitting in school wracking his brain to come up with a poem to tell Ladybug how he feels about her (and he's concerned about how she'll react -- what she wouldn't want to hear from him, and wondering what he could say to make a good impression on her). It's an internal voiceover monologue as he comes up with ideas, rejects them, and struggles with the creative process of writing a love poem that will express his sincerity to Ladybug, before ultimately giving up his task as hopeless.
I loved watching these, even though they really don't have any new animation in them. It was just great to hear what the characters are thinking, in their own words. I really wish these had been included as bonus features on the Shout Factory DVD releases of MIRACULOUS, instead of tedious minutes of "animatic" test footage with re-looped dialogue tracks overdubbed.
