Who's That Lady?

A good comics writer can keep the reader off-balance with any number of literary and/or visual devices. TB accomplishes it by employing lax, slipshod storytelling and draughtsmanship. I assume that’s Nate’s wife, and not Cayla from a hairstyle ago plus glasses. We were able to establish that Mr. Blackburn appeared in earlier Funky Winkerbean strips; can any of you FW scholars tell me when, if ever, we’ve been introduced to Mrs. Nate Green? I mean before today?
