Jane Kaczmarek May or May Not Be Joining 'Breaking Bad'

Last week Dean Norris, who plays "Breaking Bad" resident DEA agent Hank Schrader, tweeted a photo of none other than Jane Kaczmarek on the set of "Breaking Bad," posing with him and a shiner-sporting Bryan Cranston as Walter White. And earlier this week Kaczmarek herself tweeted that "Yes, it's true... I will indeed be on #BreakingBad. Can't wait for you all to see it."

Will, as some have theorized, "Breaking Bad" at last be revealed as one long, incredibly dark prequel to "Malcolm in the Middle," with Walt starting a new life under a different name as a non-drug-dealing suburban dad after getting remarried to Kaczmarek's Lois? Could Walt Jr. (RJ Mitte) turn out to be a lost half-sibling to Frankie Muniz, Justin Berfield, Erik Per Sullivan and Christopher Masterson's band of brothers?

Alas, probably not, at least not in context of the series itself. Vulture reports that "a source at the show tells us that the Lois and Hal reunion will be for the DVDs only and not one of the final episodes of the series" -- which makes sense, as that kind of meta nod to the actors' pasts might be a little jarring in what's probably going to be a very intense final eight episodes set to air this summer.
