Speaking with Michael Ausiello at TVLine’s Comic-Con studio presented by ZTE, exec producers Steven Molaro and Bill Prady shared that Sagal’s name had come up earlier in the series’ run, to serve a different purpose. But all along, the actress told the show, “She is always happy and ready to play Kaley [Cuoco]’s mom” — just as previously did on the ABC sitcom 8 Simple Rules.

The producers then go on to confirm another return for Penny’s wedding re-do, as well as tout the unlikely casting of JAck McBrayer as Penny’s drug dealer brother.
