I actually appreciated Trixie in both episodes she was in. She was obnoxious and self-centered, yes, but that was who she was, it was part of her character. We see her stray from that occasionally, and I love that as it shows that she is at least trying to change. I would love to see one final return from her, not as an antagonist at all, but attempting to be a good friend. This is unlikely to happen, but I'd love to see it. Trixie is one of my favorite side characters, and I feel like she gets a ton of unneeded hate.
