I wish I'd done the "disappearing" calling card over 2 panels... so it goes.
I don't think it was intentional, but Will and Hanna are essentially wearing the same outfit, looking more than ever like twins. It's kind of perverse! But they're finally settling into what they are to each other, being in a state of permanent familial concern and nastiness.
