Y'know, I'm genuinely surprised at the fact that anyone was even slightly worried about Barry's safety. I mean, since when does Jeph spend effort on creating a bizarre character only to stop using them after one scene?
Faye... how best to put this...? This is healthy for Dora. The old Co Datmosphere was a product of her sense of alienation and persecution. She is moving away from those neuroses and so is the shop. She just doesn't have that anger anymore and you have to admit that she's more healthy for that! Positivity helps more than negativity, as you've learned through your time with Bubbles!
Actually, you can't help but wonder if Faye's own anger reinforced Dora's as well as encouraged her negative perception of the world. Faye's absence may have contributed to Dora's progress. I hope that Faye considers this and asks hherself if changes on her own part are necessary, for her own sake.
