How I escaped my certain fate by Stewart Lee
I’ve, I’ve done this before when there’s been a kind of split in the room. Usually it creates an atmosphere of bonhomie. But tonight, it’s made it worse, hasn’t it? It’s made it worse. There’s a tension in the room that’s now ‘the gig is lost’, right? It’s lost.
Stewart Lee tries to "split" his audience during the stand-up show to create a tension. He writes that the tension created this time wasn't created as expected and the show now is lost.
The part that confuses me is that's now 'the gig is lost'.
Does "that's" mean "in other words" or "that it is"? There is no comma before it, so that why I'm not sure what "that's" connects to in this sentence.
