In the hospital, they finally have it out in a brutal fight where their heartbreak and anger tears down the walls they put up. Debbie is still hurt, yes, but that has morphed into a bitterness that borders on callous. The affair, she believes, caused her neat life to fall into disarray. Ruth rebukes the idea that Debbie even enjoyed that existence and reveals how demeaning their friendship felt to her. She knows she did an objectively bad thing, but her anger at the way Debbie would consistently belittle her and her acting career feels no less legitimate, just as Debbie's point about not wanting to feel sorry for her success in the wake of Ruth's failures also rings true. Their battle is cathartic, and, ultimately, healing. The freeness they now feel leads to the most straight-up joyful half hour of the season: A full, grainy recreation of a GLOW episode, complete with wrestling matches and songs.
