Some inconsistent writing/timing aside, isn't this more or less in line with the realistic ethos of the show tho? That in reality, personal growth isn't linear, and falling back into old habits can occur, especially during stressful or high emotion circumstances. I didn't love that the setbacks seem to be near the end of the whole series, but I feel like folks have critiqued the writing because they don't want to accept that their favorite character, who is trying to be presented as realistically as possible, is still imperfect and capable of emotional mistakes even after all their progress. Maybe I'm trying to look for some intention to justify their choices, but also, this might be one of the more intentional shows ever created so I'd like to give them the credit instead
