Yes, she will. I have an unnecessarily complicated backstory for how it ended up being Harry/Mira and not Harry/Murphy, but the short version is that, in my mind, they totally get together in later years. I picture them living together, probably Murphy moving in with the Dresdens at some point. I don't see them getting married, since both of them have had bad experiences in that department, but being very much partners and happy together in in their odd little Harry/Murphy way. I also picture Fay and Mal being the catalyst to them getting together. 'For Heaven's sake, just go kiss her, Dad!'
