From pictures I've seen from a very knowledgeable person on FB (I know), "Real Time" has been from another studio at TV City during the pandemic and the set is still up in that studio. Since it's going to be another year now before the remodeling actually starts, they could come back after the strikes--although Maher's statements lately about the strikes makes me wonder if any WGA member will want to work for him now. (In the last WGA strikes, he kept going with a monologue but no mid-show bit, "New Rules" or closing commentary, dropped the cold opening completely and moved the "Overtime" viewer Q&A into the main show with the title "Blogga Please.") I guess this time he realized he needed writers, although the decision also could've been made by Daddy Zaslav.
And I personally wonder if I will ever come back to Maher after the strikes. Even if he hates Trump, God has he really become more squirelly than before in the last few years.
