“Big Bang Theory” star returns to ABC sitcom in Tuesday’s episode

Johnny Galecki will make his big return to “Roseanne” in Tuesday’s episode of the ABC revival, titled “Darlene v. David.”

A new preview clip released on Monday reveals Galecki’s return to the series as David Healy, estranged husband to Sara Gilbert’s character Darlene and father of her children.

“Oh wow. They kept everything exactly the same as when you were kids,” David says after climbing through Darlene’ window, remarking on how little has changed in the 20 years since the show first went off the air.

According to the official synopsis, David “unexpectedly shows up for [his daughter] Harris’ (Emma Kenney) birthday after being absent for years, forcing Darlene to re-examine their relationship and the rest of the family.” In the additional clip below, he explains that he’s moving back to Lanford to be closer to his family.

Tuesday’s episode will also see the return of Estelle Parsons as Bev, Roseanne (Roseanne Barr) and Jackie’s (Laurie Metcalf) mother who has been barred from her retirement home and needs to stay with the Conners.
