Now here’s a background I actually put some effort into! (Because I could get the references without leaving my apartment…)

I, uh, wanted to make it real clear that “Bianca cooks for her roommate” was not a typical feature of their dynamic.

In retrospect, I don’t know why she has an apron. In all the years since, neither I nor any of my various apartment-mates have ever bought an apron to cook in. Logic was overridden by the universal visual signpost for “this character is cooking.”
