"She reminds me very much of all of the mothers with whom I fell in love when I was a teenager because they were lenient on all my friends."Personal Connection To The Character"I was jealous of the fact that they didn’t have curfews and was jealous of the fact that we could get drunk at their house, as long as we weren’t driving. She didn’t have any rules or regulations, a single mom, but then years go by and then in retrospect, you look back and think: 'Oh, that woman was actually quite neglectful and probably clinically depressed, right?'" Ubach joked.The Flight Attendant season 2 is expected to begin airing sometime in 2022.
