Spoilers for 12th and final season of the Bones TV show are rolling in, even though it doesn’t premiere on FOX until the mid-season. Among them is a casting news item: The Big Bang Theory‘s June Squibb will guest star in Bones, season 12, TV Line‘s Michael Ausiello reports.

After the jump, you’ll find the full Bones spoilers scoop.

Question: What guests stars are we going to see in the final season of Bones? —Mindy
Ausiello: I already told you that beloved TV vets Ed Asner and Hal Holbrook will be appearing in Season 12’s third episode. But what I didn’t tell you — because I was saving it for Ask Ausiello — is that they’ll be joined by Oscar-nominated actress June Squibb (aka Sheldon’s Meemaw on Big Bang Theory). Squibb will play a retirement home resident you do not want to make angry.

Question: Do we know yet if Bones‘ series finale (sniff) will be two hours? —Sarah
Ausiello: As of now it’s just a one-hour episode, but, you never know — Fox could schedule the penultimate episode on the same night and call it a “two-hour Bones finale event!” Meanwhile, co-showrunner Jonathan Collier is still hoping series creator Hart Hanson will “either write or co-write” the swan song (possibly with former EP Stephen Nathan). “He’s been very, very, very involved in discussing the series,” Collier adds of Hanson. “He’s the best person in history to inherit a show from because he gives you his blessing. He’s handed over the show to us, but he is also very available to us.” BONUS SCOOP: Cam and Arastoo’s nuptials will be a decidedly low-key affair. “I think [we had our] big wedding with Brennan and Booth,” says Collier. “So let’s just say that it’s going to be exciting and different.”
