Leon’s would just be music posts and pictures of swords or videos of sword fighting in general. He’d be a total asshole to everyone and never even give a fuck.
Ryan would dedicate his to film reviews and discussing literature and cinematography with others. Sometimes he’d link to TV Tropes pages or scenes from movies he’s seen.
Mary’s blog would mostly be gardening tips, reblogging photosets of various plants and the like, and sometimes link to her stories posted on Fanfiction.net.
Leia would post pictures of herself and complain about everything under the sun. Somehow, her blog is more popular than the other kids’ blogs.
