None of the options really fit my view.
I liked her and thought she had potential. That doesn't necessarily mean they should bring her back, though. If they can bring her back in a way that makes sense and actually give her an interesting story that is relevant to the overall plot, then, yes, bring her back. However, they should not bring her (or any character) back just to bring her back. I feel like there are too many characters on this show that they kept around or brought back when they had no long-term plan for what they really wanted to do with them.
