The question: Salty "The Sack" Johnson (John Morrison) is a professional wrestler assigned as GLOW's original trainer, but is fired by Sam due to creative differences.

Lorene (Lisa Ann Walter) is Debbie's mother, who takes care of Debbie's son Randy while she is out training for GLOW. Ron (Allan Havey) is Debbie's stepfather. Dale (Alex Riley) is a professional wrestler who takes the persona of "Steel Horse", a working-class hero. He admits to Debbie that his promotion's storylines were inspired by soap operas, and that he has been a fan of hers since her days in Paradise Cove. Rick (Joey Ryan) is a professional wrestler who takes the persona of "Mr. Monopoly", an arrogant business tycoon who is Steel Horse's arch nemesis and half-brother. His gimmick is a parody of "The Million Dollar Man" Ted DiBiase, and he is accompanied by his valet and Steel Horse's ex-girlfriend Crystal (Laura James), a parody of Miss Elizabeth. Michael (Daniel Polo) is Gregory's cousin and a young Russian Jewish chess champion who migrates to America. He undergoes bris during his welcome party, and upon overhearing Ruth talking about Yentl, he asks her to sing one of Barbra Streisand's songs to ease his pain.
