Uh... very sorry for not updating in so long! Don't worry; I'm not dead or anything. I've just been working almost exclusively on another project for the past few months. I didn't want to leave Brutus completely abandoned, though, so I quickly sketched up this sheet of expressions for Mirabelle to post here.
I hope to get the other project done by the end of the year, so expect more Brutus in 2017, if not sooner!
