LOS ANGELES — Last February, Jill and Faith Soloway were filming the final episode of “Transparent” here at Paramount Pictures, in the studio’s cavernous Stage 14. It was the last day of a 20-day shoot, and Judith Light , as the nettlesome matriarch Shelly Pfefferman, was tearing through “Your Boundary Is My Trigger,” a show tune-slash-primal scream about how thankless it is to be a mother, and how Shelly gives and gives and gives, and for what?

“If I could, I’d shove you back inside me,” Light sang, using her hands to show just what such a procedure might look like.

After a series of energetic takes surrounded by a chorus line of women in bras and girdles and men in long johns and bunny slippers, Light, all smiles, came over to the monitors to see how everything looked, and to hug people and call them “sweetie pie.” Despite the lively dance number, there was a palpable sense that things were coming to a close, as longtime colleagues, some in costume, some in street clothes, said their goodbyes.
