Or maybe she wants to do new characters? Hopefully?
I hope so, but now that Derick brought up the Assholes, pairing them with The Target Lady, I really think her policy has always been to quietly rebel and just stop doing recurring characters after a certain point. (The Time article suggest that.) It's weird to suddenly make it a *public* thing -- though that could also just be the AV Club pulling a headline out of a random sentence in somebody else's interview.
Anyway, I honestly hope I'm wrong.
