Yes Faye, it was nice of Dora, a courtesy that a lot of employers probably wouldn't extend to someone who wasn't also a friend. But perhaps I'm misreading the tone of that first panel; in the second one, Faye is certainly showing some awareness that she brought the situation on herself, so perhaps her comment in the first panel is meant to be more of a vague acknowledgement, in a morose and defeated tone.
In addition to hitting us right in the proverbial feels, the latest strip also brilliantly demonstrates Hanners' naivety. Endearingly, she suggests that simply asking very nicely will erase the transgression, and the betrayal of trust. If only it were that simple when we messed up big time in our lives, and only it were that simple for two of our main characters here.
At the same time though, Hanners is also a bit naive about Faye and her personality. I don't think that Hanners truly realises how abrasive, difficult, and bullying Faye can be towards other people. It's understandable, because Faye treats her better than pretty much everyone else in the cast. To Hanners, she's one of her first real friends apart from Station, someone who has helped her with her anxiety and have what most of us would consider a normal and healthy social life. As such, she holds Faye in very high regard.
Faye hasn't been nearly as warm or supportive towards other people in the past though, and her character flaws have certainly been described and discussed in length. Hanners was
happy when Faye was made assistant manager, subsequently shocked by Penelope and Cosette being ready to immediately quit, and
insisted Faye be given a chance, because she's not truly aware of how horrible Faye can be to other people, nor why other employees at CoD would find her being (officially) in a position of power off-putting and undesirable.
I also still think that was an eye-opening moment for Dora, a reason why she's lost patience with Faye. Before that, I'm not sure that she really appreciated or understood that not everyone had the same tolerance for Faye that she did, and that some her quirks were that much of a problem for other people. It's understandable on both hers and Hanners parts though, not to mention realistic. When you are friends with a difficult person, and aren't bearing the brunt of their less than admirable traits, you're not truly aware of the extent of them. I think Dora now is, but Hanners isn't, because it's filtered by her history with Faye and the way she's treated by her.
